Remove syscall module.

This module merely contained FFI declarations, and only enough to
implement memfd_create() and pivot_root() wrapper functions in
nix. Since these declarations are redundant with equivalent FFI
declarations in libc, we'll remove them here. In the future, any
syscall-related wrapper function will be implemented directly and
utilize libc for FFI declarations as we cannot generically expose
a type-safe `syscall()` because of its variadic argument list.
