Fix #78183: finfo_file shows wrong mime-type for .tga file

I built the magic.mgc file based on https://github.com/file/file/tree/FILE5_31 and applied all changes from magicdata.patch including file/file@bb421c4#diff-5c8aa65000f916c2f4b5c29c808ea851.

@jdoubleu looks good, thanks for the PR! Usually ext/fileinfo/tests/magic* should be updated as well, the text version for the tests, but probably that's not required in this case as the test doesn't use it. Does the test pass with upper PHP branches? The test only, as no data update should be needed there. I'll need to check that before merging.

Thanks.

Yes, I totally agree. For the sake of completeness, I updated the ext/fileinfo/tests/magic* files. However, they did not match the text version of all magicdata in FILE5_31 after the magicdata.patch was applied. So I only added changes for this PR to them.

When merging into PHP7.3 or later the magicdata.patch patch can be removed, because PHP7.3 uses FILE5_33, which already includes this fix. However the tests can still be kept.

Merged as 855bbc8. The test magic update was not really necessary, but thanks in any case!
