Emulate sigprocmask(), not sigsetmask(), on Windows.
Since commit a65e0864, we've required Unix systems to have
sigprocmask(). As noted in that commit's message, we were still
emulating the historical pre-standard sigsetmask() function in our
Windows support code. Emulate standard sigprocmask() instead, for
consistency.
The PG_SETMASK() abstraction is now redundant and all calls could in
theory be replaced by plain sigprocmask() calls, but that isn't done by
this commit.
