selftests/nolibc: add static assertions around time types handling
The nolibc system call wrappers expect the libc types to be compatible
to the kernel types.
Make sure these expectations hold at compile-time.

tools/nolibc: remove time conversions
Now that 'struct timespec' and 'struct __kernel_timespec' are
compatible, the conversions are not necessary anymore.
The same holds true for 'struct itimerspec' and 'struct
__kernel_itimerspec'.
Remove the conversions.

tools/nolibc: prefer explicit 64-bit time-related system calls
Make sure to always use the 64-bit safe system calls
in preparation for 64-bit time_t on 32-bit architectures.
Also prevent issues on kernels which disable CONFIG_COMPAT_32BIT_TIME
and therefore don't provide the 32-bit system calls anymore.

tools/nolibc: remove __nolibc_enosys() fallback from time64-related functions
These fallbacks where added when no explicit fallbacks for time64 was
implemented. Now that these fallbacks are in place, the additional
fallback to __nolibc_enosys() is superfluous.

tools/nolibc: add timerfd functionality
This is used in various selftests and will be handy when integrating
those with nolibc.
