fbbb19f244 Fix cases where a CPU ucode version is not found in $procfs/cpuinfo. (#246) 
* Fix cases where a CPU ucode version is not found in $procfs/cpuinfo.

When running whithin a virtual machine, it seems like $procfs/cpuinfo doesn't contain
a 'microcode' line, which triggers a script runtime error.
Fall back to '0x0' in this case, as other part of the script seems to already this
as a default value anyway.

* Double quote to prevent globbing and word splitting.

349d77b3b6 Fix kernel detection when /lib/kernel exists on a distro (#252) 
Commit b48b2177b7 ("feat: Add Clear Linux Distro (#244)") broke kernel
detection for distros using that directory for other purposes than
storing the kernel image.

Example:
 # pacman -Qo /lib/kernel
/usr/lib/kernel/ is owned by mkinitcpio 24-2
/usr/lib/kernel/ is owned by systemd 239.2-1

96798b1932 chore: add SPDX GPL-3.0 license identifier (#245) 
The spectre-meltdown-checker.sh file is missing licensing information.
The SPDX identifier is a legally binding shorthand, which can be
used instead of the full boiler plate text.

42a3a61f1d Slightly improved Docker configuration (#230) 
* Listed the required volumes in the Dockerfile.

* Added docker-compose.yml for convenience as users won't need to manually
specify volumes and stuff when running through docker-compose.

Adjusted README.md to reflect this change.

* Cortex A8 Vulnerable

Arm Cortex A8 is vulnerable to variants 1 & 2  (https://developer.arm.com/support/arm-security-updates/speculative-processor-vulnerability)

Part number is 0xc08 (https://developer.arm.com/docs/ddi0344/b/system-control-coprocessor/system-control-coprocessorregisters/c0-main-id-register)

False negative reported by @V10lator in #206

* ARM Cortex A12 Vulnerable to 1&2

https://developer.arm.com/support/arm-security-updates/speculative-processor-vulnerability

* A76 vulnerable to variant 4

All arch 8 cortex A57-A76 are vulnerable to variant 4.

https://developer.arm.com/support/arm-security-updates/speculative-processor-vulnerability

* Whitelist variant4 nonvuln Arms

* ARM Cortex Whitelist & Cumulative Blacklist

Applies all information about vulnerabilities of ARM Cortex processors (from https://developer.arm.com/support/arm-security-updates/speculative-processor-vulnerability).

Whitelist & blacklist approach, using both vulnerable and non vulnerable status for each identified CPU, with vulnerabilities tracked cumulatively for multi CPU systems.
