move signal.h REG_* macros under _GNU_SOURCE protection
they were accidentally exposed under just baseline POSIX, which is a
big namespace pollution issue. thankfully glibc only exposes them
under _GNU_SOURCE, not under any of its other options, so omitting
the pollution in the default _BSD_SOURCE profile does not hurt
application compatibility at all.
