gsmtap_util: SNR can be negative, use a signed integer
In 'struct gsmtap_hdr' field 'snr_db' is defined as a signed integer,
however all functions that fill this structure accept an unsigned
integer. This is wrong, because SNR can be negative.
Let's use 'int8_t' instead of 'uint8_t'. Changing from unsigned
to signed should be relatively safe compared to the opposite.
Most of the callers I am aware of always do pass 0 anyway.
