[MIPS] Reimplement syscall to invoke the system call directly
Some MIPS kernels do not correctly restart interrupted system calls that
have been invoked using the indirect syscall (NR_syscall).
The simplest workaround is to handle the indirection in userland and then
call the required system call directly.
