Fix capability/property checking methods to handle multi-bit capabilities.

Some capabilities, such as CAPABILITY_SUPPORTS_VT_LOCAL_BIDIRECTIONAL
are defined in terms of other capabilities; eg:
CAPABILITY_SUPPORTS_VT_LOCAL_RX | CAPABILITY_SUPPORTS_VT_LOCAL_TX

The current capability logic will return TRUE if checking for
CAPABILITY_SUPPORTS_VT_LOCAL_BIDIRECTIONAL and either of the TX or RX bits
is on; which is incorrect.  Yay cts tests for finding this.
