Subject: [PATCH] missing.h: drop clock_nanosleep() replacement

Since uClibc-ng commits 68628fe7d463541bf3c33da6b214e63c0cc9feed
("librt: declare clock_nanosleep not only for NPTL") and
ddbb03e77ac1a48740688814b82f45c97ee81f37 ("librt: clock_nanosleep
could be even used without threads"), clock_nanosleep() is always
provided by uClibc, regardless of the thread implementation (none,
linuxthreads, nptl). These commits will be part of the upcoming 1.0.31
release of uClibc-ng.

Thanks to this, we can drop the replacement clock_nanosleep()
implementation added by linuxptp. Without this, linuxptp fails to
build with:

missing.h:117:19: error: static declaration of 'clock_nanosleep' follows non-static declaration
