[yocto] [PATCH] nightly-oe-selftest.conf: instruct to sign rpm packages serially

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

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

Under high workloads, there are situations where the rpm file-chunk
signing fails due to lack of memory resouces, so indicate the
system to sign serially. The following log is what it has been
observed recently:

    ERROR: bc-1.06-r3 do_package_write_rpm: Function failed: Failed to sign RPM packages: gpg: signing failed: Cannot allocate memory
    gpg: signing failed: Cannot allocate memory
    error: gpg exec failed (2)
