Moves a large chunk of non-cancellable linux syscalls to libzigc, not all have been moved as some (like e.g ftruncate) are broken in x86_64 with the x32 abi.

Also adds _Exit to std.c and some syscalls that were missing in std.os.linux.

The vast majority of libc functions return `c_int` for the return value,
when setting errno. This utility function is for those cases.
Other cases can hand-roll the logic, or additional helpers can be added.
