Allow file type changes if file is classified as MOVED_MODIFIED

[lolrepeatlol]

At times, the Linux kernel can encounter modifications to file types that will change their SourceFileType from SOURCE to OTHER, as seen in #256:

diff --git a/arch/s390/crypto/crc32be-vx.S b/arch/s390/crypto/crc32be-vx.c
similarity index 56%
rename from arch/s390/crypto/crc32be-vx.S
rename to arch/s390/crypto/crc32be-vx.c

This change to the code should account for those modifications, provided that the FileChangeType is already set as MOVED_MODIFIED.

Important notes:

• At this time, the code is lightly tested. The change allows the code to get further in the set of commits provided in #256 by addressing the AssertionError.
  • Without the fix from #275, kmax will run into the same error detailed in #274.
  • ~~That being said, it's worth noting that applying the commits brought up in the issue will cause the program run into a different error after applying this change. I currently believe the error is unrelated, but I will continue debugging & testing before turning this into a full PR (some debug prints added as well):~~

I confirmed that the above error is an entirely separate bug in #277.
