[OE-core] [PATCH 1/2] sign_rpm.bbclass: force rpm serial signing

[leonardo.sandoval.gonzalez at linux.intel.com]

From: Leonardo Sandoval <leonardo.sandoval.gonzalez at linux.intel.com>

Newer versions of gpg (at least 2.1.5 and 2.2.1) have issues when signing occurs in parallel
so (unfortunately) the signing must be done serially. Once the upstream problem is fixed,
this patch must be reverted, otherwise we loose all the intrinsic parallelism from
bitbake.
