Brutally added patch command after download.

I've been finally able to test it and the PRE_PATCH_HOOK does not work
seems it's never triggered.
I tried also th POST_RSYNC_HOOK that works but still patch is not
applied.
I think that patch is not detected (odd, patch naming seems complient)
or since source code is not downloaded buildroot thinks that patch is
not needed, couldn't sort it out.
This problem is referenced in many different issues, some of them:
Bluetooth: hci0: Frame reassembly failed (-84)

Error communicating with local bluetooth adapter (RPi3)

Solution seemed to reeduce the boud rate of the serial connection to BT
on rpi3b where flow control is missing.
The patch to the original btuart file is to reduce the baudrate only for
rpi3b models where flow control is missing:
- $HCIATTACH /dev/serial1 bcm43xx 921600 noflow - $BDADDR
+ $HCIATTACH /dev/serial1 bcm43xx 460800 noflow - $BDADDR
I'm not a buildroot expert but the best way seemed to move the
upstream btuart download in a PRE_PATCH_HOOK so that standard
buildroot way of patching can be applied.
