[OE-core] [PATCH 21/22] oeqa/selftest/recipetool.py: Use regex to match warning line

[Richard Purdie]

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

We are observing cases (see below) where the 'WARNING:' prefix is not at the
beginning of a line, so instead of expecting it in the beginning, match it with
a regex.
