x86/cpufeatures: Flip the /proc/cpuinfo appearance logic
I'm getting tired of telling people to put a magic "" in the
#define X86_FEATURE /* "" ... */
comment to hide the new feature flag from the user-visible
/proc/cpuinfo.
Flip the logic to make it explicit: an explicit "<name>" in the comment
adds the flag to /proc/cpuinfo and otherwise not, by default.
Add the "<name>" of all the existing flags to keep backwards
compatibility with userspace.
There should be no functional changes resulting from this.
