OpenTTD does not find GM.CAT when named uppercase. #8313

Yeah, this issue doesn't occur on Windows. I checked the baseset descriptions and it would appear that these files have incorrectly capitalized filenames:
As defined by both the readme and the original games' file structures, the DOS files should be uppercase and the Windows files should be lowercase; and as defined by just the readme, the TTO file should be uppercase. |

Basically, systems that are case sensitive would otherwise not been able to load without changing the cases. OpenTTD initial tries the casing as given by the obg/obm/obs files, and if that fails tries lowercase too. So for those who already have the files lowercase, nothing changes. For those that install fresh from TTO, it should now work out-of-the-box.

DOS did not have cases in filenames. Different OS interpret them as either all-lowercase or all-uppercase. So we try both. All-uppercase is done by the obg/obm/obs files, and if opening those files fail, OpenTTD will automatically retry the all-lowercase variant. So for those who already have the files lowercase, nothing changes. For those that install fresh from TTO, it should now work out-of-the-box.

Version of OpenTTD
OpenTTD 1.10.3
Expected result
When I copy the GM.CAT file from the DOS version to get the original music it should be detected when named uppercase.
Actual result
The game does not find GM.CAT and does not show the music set in the settings.
Steps to reproduce
Pretty much what the title says: Copy the GM.CAT file from the original DOS version to the baseset/ folder. Probably only happens on Linux since Windows is case insensitive.
So what confused me most about this is that GM.CAT is clearly mentioned as uppercase in the README.md while the game is looking for a file in lowercase. Either it should be mentioned correctly in the README.md or the game should look for both filenames.
