sysklogd: fix build on musl

This commit add a stack of small patches that make sysklogd build fine
with the musl C library. Build with uClibc and glibc has been tested
with those patches applied as well.

The first patch is slightly rework (better description and capital
letter to the title) in preparation for upstream submission.

+Subject: [PATCH] Add missing headers for open() flags
+
+Both pidfile.c and syslog.c use open() and its flags, but forgets to
+include all relevant headers, causing build failures with the musl C
+library.
