Tim Duesterhus 29d2e8aa9a BUG/MINOR: lua: Properly initialize the buffer's fields for string samples in hlua_lua2(smp|arg) 
`size` is used in conditional jumps and valgrind complains:

Found while investigating issue #306.

A variant of this issue exists since 55da165301,
which was using the old `chunk` API instead of the `buffer` API thus this patch
must be backported to HAProxy 1.6 and higher.
