oprofile: fix nanosleep() issue on non-threaded toolchains

Subject: [PATCH] Include <time.h> for nanosleep()

The nanosleep() function prototype is in <time.h>, so this header file

should be included whenever nanosleep() is used. Not including it

causes some issues when building OProfile against a non-thread capable

version of the uClibc C library, probably because in such situation,

<time.h> does not get included by another header.
