DigiPi hotfix: 100% CPU when using bluetooth TNC / aprsdroid

[Craig]

Hi Guys, there's a bug in the stock bluez rfcomm binary that drives the CPU to
100% if, and only if, you have a bluetooth connection to the DigiPi TNC (ie aprsdroid).

I patched rfcomm to loosen up the polling loop and it's well behaved.  This fix is
optional unless you've got some compromised thermals or need extra CPU power
for any reason.  I thought I'd make this available before the next release of DigiPi
since it's annoying.
