[RFA] make gdb.base/sigall.c more robust

One environment in which I run the gdb testsuite has a few signals blocked
at the start. If tcl/expect/bash had the ability to unblock signals it might
be preferable to unblock the signals there (I couldn't find any),
but OTOH testcases should be reasonably robust.

* gdb.base/sigall.c (main): Ensure all signals aren't blocked.
