BUG/MINOR: pattern: prevent const sample from being tampered in pat_match_beg()

This is a complementary patch to a68affeaa ("BUG/MINOR: pattern: a sample
marked as const could be written"). Indeed the same logic from
pat_match_str() is used there, but we lack the check to ensure that the
sample is not const before writing data to it.

It could be backported to all stable versions.
