x86/cpufeature: Add bug flags to /proc/cpuinfo

Browse source

commit 80a208bd39 upstream.

Dump the flags which denote we have detected and/or have applied bug
workarounds to the CPU we're executing on, in a similar manner to the
feature flags.

The advantage is that those are not accumulating over time like the CPU
features.
