BUG/MINOR: lua: set buffer size during map lookups

This size is used by some pattern matching to determine if there
is sufficient room in the buffer to add final \0 if necessary.
If the size is not set, the conditions use uninitialized value.

Note: it seems this bug can't cause a crash.

Should be backported until 2.2 (at least)
