Bluetooth: fix BT dependency for submodules

Browse Source 
The modules rfcomm (BT_RFCOMM), bnep (BT_BNEP), hidp (BT_HIDP), and
bluetooth_6lowpan (BT_6LOWPAN) are dependent on the bluetooth module
(BT, tristate) only transitively through the boolean BT_BREDR for the
first three and through the boolean BT_LE for the bluetooth_6lowpan.
Therefore, the modules can be selected as built-in even if the BT=m.
The combination of BT=m and =y for the said modules leads to the kernel
build system silently ignoring those modules, without ever compiling
them as built-in or as loadable modules.

Add BT as a direct dependency to the Kconfig of rfcomm, bnep, hidp, and
bluetooth_6lowpan. The modules set to =y when BT=m will default to =m,
rather then getting silently ignored by the build system.
