[LTP] [PATCH] syscalls/clock_adjtime: Fix compiler error

[Yang Xu]

'ADJ_OFFSET_SS_READ' 'ADJ_NANO' 'STA_NANO' and 'ADJ_MICRO' are not defined on
some old distros, so add them into 'include/lapi/posix_clocks.h' to fix it.

These macros are introduced by the following commit:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=52bfb36
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=eea83d8

sys_clock_adjtime are introduced by the following commit:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=339dc50
