tools/nolibc: fix error return value of clock_nanosleep()
clock_nanosleep() returns a positive error value. Unlike other libc
functions it *does not* return -1 nor set errno.
Fix the return value and also adapt nanosleep().
Fixes: 7c02bc4088af ("tools/nolibc: add support for clock_nanosleep() and nanosleep()")
