Avoid prctl(PR_PAC_RESET_KEYS) on devices without PAC support.

Processes loaded from vendor partitions may have their own sandboxes
that would reject the prctl. Because no devices launched with PAC
enabled before S, we can avoid issues on upgrading devices by checking
for PAC support before issuing the prctl.
