Allow the location of capabilities.conf to be configured. Also allow a per-abi syscall prefix to be configured with the abi_func_prefix syscalls.conf variable and check syscalls against entries in capabilities.conf with and without the prefix amended. Take advantage of these two features to allow use shared capabilities.conf between the default syscall vector and the freebsd32 compatability layer. We've been inconsistent about keeping the two in sync as evidenced by the bugs fixed in r340294. This eliminates that problem going forward.
