Fix detection of CVE-2018-3615 (L1TF_SGX) (#253) 

* Add another location of Arch Linux ARM kernel

* Fix detection of CVE-2018-3615

We change the value of variantl1tf in the line directly before so its
value will never be "immune". Instead we can directly use the value of
variantl1tf to initialize variantl1tf_sgx.
