Brooks Davis df501bac69 syscalls.master: switch to CAPENABLED flags
Switch the main syscall table to use CAPENABLED flags rather than
capabilities.conf.  This avoid synchronization issues between
syscalls.master and capabilities.conf (e.g. when renaming a syscall
during development).

For now, move capabilities.conf to sys/compat/freebsd32 and use it
there.  Use of sys/compat/freebsd32/syscalls.master should be replaced
by makesyscalls.lua enhancements to allow the main one to be used.

This change results in no changes to generated files after running
`make sysent`.
