[OE-core] [PATCH 1/1] classes/sstate: fix regression affecting buildhistory

[Paul Eggleton]

SSTATEPOSTINSTFUNCS needs to be set with ?= here - if it's = it'll wipe
out what is set in that variable in buildhistory, which ends up being
parsed earlier than the statement in sstate.bbclass. This fixes
buildhistory no longer recording package information since OE-Core
revision 9d659c6f20fa4a141b491c62a3ef0dfb1f896d9c.
