[PATCH 19/21] trailer: move config lookup out of parse_trailer

[Anders Waldenborg <anders@0x63.nu>]

); SAEximRunCond expanded to false

This may be seen as making it worse adding code duplication. But will
hopefully make different handling for config lookups easier.

No functional change intended.
