tools/nolibc: avoid using plain integer as NULL pointer
While an integer zero is a valid NULL pointer as per the C standard,
sparse will complain about it.
Use explicit NULL pointers instead.

tools/nolibc: provide the portable sys/select.h
Modern programs tend to include sys/select.h to get FD_SET() and
FD_CLR() definitions as well as struct fd_set, but in our case it
didn't exist.
The definitions were moved from types.h to sys/select.h, which is
now included from nolibc.h, and the sys_select() definition moved
there as well from sys.h.

Since commit fb01ff635efd ("tools/nolibc: keep brk(), sbrk(), mmap()
away from __sysret()") the implementation of mmap() does not use the
__sysret() macro anymore.
Remove the outdated comment.

tools/nolibc: drop wait4() support
Not all architectures implement the wait4() syscall. It can be
implemented in terms of the waitid() syscall, but that would require
some rework of the other wait-related functions in wait.h.
As wait4() is non-standard and deprecated, remove it.

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.

Newer architectures like riscv 32-bit are missing sys_wait4().
Make use of the fact that wait(&status) is defined to be equivalent to
waitpid(-1, status, 0) to implement it on all architectures.

tools/nolibc: fall back to sys_clock_gettime() in gettimeofday()
Newer architectures (like riscv32) do not implement sys_gettimeofday().
In those cases fall back to sys_clock_gettime().
While that does not support the timezone argument of sys_gettimeofday(),
specifying this argument invokes undefined behaviour, so it's safe to ignore.
