Andrew G. Morgan 1209726ce9 security: filesystem capabilities: fix CAP_SETPCAP handling ...

The filesystem capability support meaning for CAP_SETPCAP is less powerful
than the non-filesystem capability support.  As such, when filesystem
capabilities are configured, we should not permit CAP_SETPCAP to 'enhance'
the current process through strace manipulation of a child process.
