Remove unused sysdeps/unix/sysv/sigaction.c

- Subject: Remove unused sysdeps/unix/sysv/sigaction.c
The file sysdeps/unix/sysv/sigaction.c is unused: Hurd does not use
sysdeps/unix/sysv, Linux has its own sigaction.c and this file is not
used via #include from elsewhere.
I propose this patch to remove this unused file. Tested x86_64.
