check: make sure all files outside contrib/ include "config.h" first. And turn "" includes into full-path (which makes it easier to put config.h first, and finds some cases check-includes.sh missed previously). config.h sets _GNU_SOURCE which really needs to be done before any '#includes': we mainly got away with it with glibc, but other platforms like Alpine may have stricter requirements.

This has several knock on benefits: - We remove the repeated tal_count/tal_bytelen calls on the script, in particular the redundant calls that result when we must check for multiple types of script - which is almost all cases. - We remove the dependency on the memory being tal-allocated (It is, in all cases, but theres no reason we need to require that). - We remove all cases where we create a copy of the script just to id it. - We remove all allocations for non-interesting scripts while iterating block txs in process_getfilteredblock_step1(). - We remove all allocations *including for potentially interesting scripts* in topo_add_utxos().
