[OE-core] [PATCH 1/2] selftest/commands: extend variable regex to include A_B variable notation

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

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

This change allows quering for variables with the format A_B, i.e.
PREFERRED_PROVIDER_virtual/kernel instead of just A.
