[OE-core] [PATCH v3 39/52] oeqa/selftest: verify that devtool can use plugins in other layers

[Joshua Lock]

From: Ross Burton <ross.burton at intel.com>

In selftest we want to exercise devtool's ability to use plugins from other
layers, so add a basic command to reverse a string to meta-selftest and a test
in oe-selftest to call it.
