dan sinclair fb5a492787 Fix inclusive language presubmit 
The current presubmit has the filter inverted so it would only attempt
to match the filtered files. The file name also has to be converted to
`LocalPath` otherwise it's attempting to compare a python object to a
string and always fails to match.

# When upgrading to CMake 3.11 we can remove DAWN_PLACEHOLDER_FILE because source-less add_library
# becomes available.
# When upgrading to CMake 3.12 we should add CONFIGURE_DEPENDS to DawnGenerator to rerun CMake in
# case any of the generator files changes. We should also remove the CACHE "" FORCE stuff to
# override options in third_party dependencies. We can also add the HOMEPAGE_URL
# entry to the project `HOMEPAGE_URL "https://dawn.googlesource.com/dawn"`
