[PATCH v1] kunit: relax regex for .config entries to allow spaces

[Brendan Higgins]

From: Daniel Latypov <dlatypov@xxxxxxxxxx>

kunit parses .config in the `build_reconfig()` of `run_tests()`.
Problematically, the current regex '^CONFIG_\w+=\S+$' does not allow for
spaces anywhere after the "=", even the option is a string.

So kunit will refuse to run if the existing .config has something like
  CONFIG_CMDLINE="something and_something_else"
even if kunit.py will drop this entry when it regenerates the .config!

So relax the regex to allow entries that match `CONFIG_\w+=".*"` as a
minimal change. The question remains as to whether we should do any
validation of the string after the "=", however.
