SCI32: Remove backslashes from PQ:SWAT extra save game files

The original interpreter created subdirectories for each in-game
profile, but copying this behaviour would add a lot of
superfluous complexity to the save game system in ScummVM, and
may not be portable to all supported platforms. Instead, when the
game tries to save its files to a subdirectory, the backslash in
the file name is replaced with an underscore so it can be created
successfully on filesystems where backslash is an illegal file
name character.

This has a side-effect of causing all save games to be displayed
under all profiles, instead of just the ones "belonging" to a
particular profile, but this seems like a reasonable trade-off
given that there is no reason to play this game with more than one
profile.
