[PATCH 2/2] posix: add clock_nanosleep and tests

Looks good except for the minor issue that in the nanosleep file there is
a mix of (X) and ( X ) for conditionals and method invocations. Fix that
and commit.

FWIW while your head is in clocks, the clock attribute on condition
variables
has been added but is not currently used. I don't know if it has a ticket
offhand.
