BUG/MEDIUM: stick-table: properly convert binary samples to keys

The binary sample to stick-table key conversion is wrong. It doesn't
check that the binary sample is writable before padding it. After a
quick audit, it doesn't look like any existing sample fetch function
can trigger this bug. The correct fix consists in calling smp_make_rw()
prior to padding the sample.

This fix should be backported to 1.6.
