common/l1ctl.c: fix: use signed type for TA in l1ctl_tx_param_req()

Despite the correct range of Timing Advance value is [0..63],
there is a special feature in OsmocomBB which allows one to
simulate the distance between both MS and a BTS by playing
with the signal delay.

It was discovered that l1ctl_tx_param_req() is using an unsigned
'uint8_t' type for Timing Advance value, while other code and
L1CTL protocol is using signed 'int8_t'. This may result in
distortion of negative values, so let's fix this!
