devices: fs: Use 32-bit uid/gid values on arm The setres{u,g}id and the gete{u,g}id system calls on arm use 16 bit values for uid_t and gid_t. This causes the kernel to interpret a uid/gid of 65535 as -1, which means do nothing. Use the 32-bit variants of these system calls instead so that we can use 32-bit values. Normally, libc would take care of hiding these kinds of implementation details but since we can't use the libc wrappers for these system calls, we have to do it ourselves.

In most cases the rules are redundant to common_device.policy. BUG=None TEST=Ran compile_seccomp_policy.py until it stopped complaining.
