[OE-core] [PATCH 1/2] oeqa/core/loader.py: fix re for module

[Robert Yang]

Fixed:
$ oe-selftest -r eSDK.oeSDKExtSelfTest.test_image_generation_binary_feeds
Traceback (most recent call last):
[snip]
  File "/workspace2/lyang1/poky/meta/lib/oeqa/core/loader.py", line 49, in _built_modules_dict
    module_name, class_name, test_name = m.groups()
AttributeError: 'NoneType' object has no attribute 'groups'

The old code assumed the arg should be:
module.Class.test

Note about the module and Class, the lower and upper cases matters, which can't
handle the testcases like eSDK.oeSDKExtSelfTest.test_image_generation_binary_feeds
and gotoolchain.oeGoToolchainSelfTest.test_go_dep_build. Use a new re to fix
the problem, now all of the following commmands can work:
$ oe-selftest -r eSDK
$ oe-selftest -r eSDK.oeSDKExtSelfTest
$ oe-selftest -r eSDK.oeSDKExtSelfTest.test_image_generation_binary_feeds
