[arm-allstar] chan_simpleusb minor bug fixes

[Doug Crompton]

An update tonight fixed two bugs in simpleusb both of which are rarely used
but needed to be fixed.

The TXCTCSS method had a bug that when COS and CTCSS were turned on CTCSS
was on all the time. The fix turns on CTCSS only when PTT is asserted.

The PTT invert/non-invert did not take immediate effect and required a
keyup condition to switch modes. This also caused the PTT to key the radio
at boot when the PTT was in non-invert or active high mode until Asterisk
started and asserted PTT.  Most everyone uses PTT in invert or active low
so this would rarely be an issue but it has been this way since forever and
needed to be fixed.

This is version 1.5.3-54.  Update using the ADMIN menu item 1.
