[2.1.20] SRB2 don't use custom home folder for save games created by a mod.

[SteelT]

System Info:
Fedora 26 64-bit

Method:

• Running the game with the following:

./lsdl2srb2 -home /run/media/steelt/Ark -file scr_subarashii_v1-2.wad

Expected behavior:

SRB2 would read/write the files to the custom home folder.

Actual behavior:
SRB2 would read/write the files to the same folder the game is in.

This only happens with mods that have a custom gamedata set, by the way, in vanilla, it repects the custom home folder location and read/writes to the set folder.

This also only happens with .ssg files, it can save .dat files to the set folder just fine.


Notes:
This probably affects mac users too, who knows.
