rpm: opendb before rpmverifyscript to avoid null point input
If the command is "rpm -V" and the return value of (headerIsEntry(h, RPMTAG_VERIFYSCRIPT)
|| headerIsEntry(h, RPMTAG_SANITYCHECK)) located in /lib/verify.c is true, it will call
rpmpsmStage function(rpmVerifyScript->rpmpsmScriptStage->rpmpsmStage) and occur segment
fault because of null point(rpmtsGetRdb(ts) == NULL and rpmtsGetRdb(ts)->db_txn).
So we open rpmdb to avoid bad input when find headerIsEntry true.
workflow:
main()->rpmcliVerify()->rpmcliArgIter()->rpmQueryVerify()->rpmgiShowMatches()->showVerifyPackage()->
rpmqv.c verify.c query.c query.c verify.c(headerIsEntry)
rpmVerifyScript()->rpmpsmScriptStage()->rpmpsmStage()-> rpmtxnCommit(rpmtsGetRdb(ts)->db_txn);
verify.c psm.c psm.c psm.c
