[OE-core] [PATCH] oeqa/selftest/signing: use temporary rpmdb

[Markus Lehtonen]

Use temporary rpmdb when importing gpg public key and checking rpm
signature. This patch should fix a problem where test_signing_packages()
sometimes fails with
"pmdb: BDB1540 configured environment flags incompatible with existing
 environment"
