x86/spectre: Report get_user mitigation for spectre_v1
 
BugLink: http://bugs.launchpad.net/bugs/1748072

commit edfbae53dab8348fca778531be9f4855d2ca0360

Reflect the presence of get_user(), __get_user(), and 'syscall' protections
in sysfs. The expectation is that new and better tooling will allow the
kernel to grow more usages of array_index_nospec(), for now, only claim
mitigation for __user pointer de-references.
