y2038: Convert thrd_sleep to support 64 bit time

Browse Source 
The thrd_sleep function has been converted to support 64 bit time.
It was also necessary to provide Linux specific copy of it to avoid
problems on i686-gnu (i.e. HURD) port, which is not providing
clock_nanosleep() supporting 64 bit time.

The thrd_sleep is a wrapper on POSIX threads to provide C11 standard
threads interface. It directly calls __clock_nanosleep64().

Build tests:
./src/scripts/build-many-glibcs.py glibcs
