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] Remove include of <linux/time.h>
+
+klogd.c and ksym_mod.c currently include <linux/time.h> if GLIBC is not
+defined. Unfortunately, this breaks badly with the musl C library: this
+C library is not glibc so it doesn't define GLIBC, but it does have a
+definition of "struct timespec" in its header file, which conflict with
+the one provided by the Linux kernel headers.
+
+So, this commit simply gets rid of this header inclusion.
