[PATCH] core/loader.py: fix regex to include all available test cases

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

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

Some test cases (i.e. eSDK.oeSDKExtSelfTest*) does not match with current regex,
fix it to accept these (and previous ones).

Without it, the following runtime exception is observed when executing eSDK
selftest (oe-selftest -r eSDK)

    Traceback (most recent call last):
      File "/openembedded-core/scripts/oe-selftest", line 70, in <module>
        ret = main()
      File "/openembedded-core/scripts/oe-selftest", line 57, in main
        results = args.func(logger, args)
