bdwgc: Include signal.h instead of hard asm/sigcontext.h

All cases are about glibc and for non-glibc systems it falls back to
last else choice which still is glibc's older version, ideally it
should have a case where libc != glibc

+Subject: [PATCH] fix build with musl
+
+signal.h already includes bits/sigcontext.h
+Documentation seems to indicate that if you need the definitions in
+sigcontext.h, you are supposed to include signal.h and not sigcontext.h.
+
+a good fix should be to remove glibc
+specific understanding, in those ifdef's
