The definitions of timeval(), timespec() and timezone() conflict with
linux/time.h when building, so this commit takes them directly from
linux/time.h. This is a port of nolibc's upstream commit dc45f5426b0c
to the Linux kernel.

Some architectures like arm64 do not implement poll() and have to use
ppoll() instead. This commit therefore makes poll() use ppoll() when
available. This is a port of nolibc's upstream commit 800f75c13ede to
the Linux kernel.

Some archs such as arm64 do not have fork() and have to use clone()
instead. This commit therefore makes fork() use clone() when
available. This requires including signal.h to get the definition of
SIGCHLD. This is a port of nolibc's upstream commit d2dc42fd6149 to
the Linux kernel.

The getpgrp() syscall is not implemented on arm64, so this commit instead
uses getpgid(0) when getpgrp() is not available. This is a port of
nolibc's upstream commit 2379f25073f9 to the Linux kernel.

A recent boot failure on 5.4-rc3 on arm64 revealed that sys_dup2()
is not available and that only sys_dup3() is implemented. This commit
detects this and falls back to sys_dup3() when available. This is a
port of nolibc's upstream commit fd5272ec2c66 to the Linux kernel.

As suggested by Ingo, this header file might benefit other tools than
just rcutorture. For now it's quite limited, but is easy to extend, so
exposing it into tools/include/nolibc/ will make it much easier to
adopt by other tools.
The mkinitrd.sh script in rcutorture was updated to use this new location.
