Bug description
When testing pylint against latest astroid in repo, there are regression failures. This is tied to an attempt to fix import paths in pylint-dev/astroid#2589 that is needed to support source-roots fallback #9967 and also clean up the logic.
The following is the output against the latest astroid repo:
=============== 6 failed, 1891 passed, 266 skipped, 5 xfailed in 99.23s (0:01:39) ================
One of the failures is in TestExpandModules.test_expand_modules:

The root cause is this line here. This code is making an incorrect assumption that "." is supposed to be current directory and is understood by modutils.modpath_from_file when in fact this api doesn't have any notion of "." being current directory. I tried changing "." to os.getcwd() and this case gets fixed BUT then other tests start breaking. At least a couple of them appear to be false assumptions around what the qualified module names need to be. I will need time to fully understand it.
In the meantime, can I change modutils.modpath_from_file to have a flag (called say prepend_additional_paths) that allows me to introduce this new (what I think is correct behavior) and use this for #9967 while keeping old behavior if prepend_additional_paths is false? We can slowly analyze the failures, fix the tests and decide if we want to break the backwards compatibility in the future.
