Subject: [PATCH] fix: read AdvanceMAME's dir_rom list on RetroPie

RetroPie writes dir_rom $romdir/mame-advmame:$romdir/arcade into the
rc of each AdvanceMAME build (advmame.sh:100, configure_advmame being
called by the 1.4 and 0.94 modules too). _search_list_in_roms split
every list on ';', so the line was dropped and the sets landed at the
BIOS root, where no build reads them.

Each program's separator is now read from its own code: AdvanceMAME
strtoks dir_rom on file_dir_separator(), ':' on Linux, in the three
builds RetroPie ships (advance/linux/file.c:138-141, advance/osd/
fileio.c:696-699 at 96237a5, 685-688 at advancemame-1.4, 640-643 in
advancemame-0.94.0). MAME splits on ';' (src/emu/fileio.cpp:56, 64,
112 at mame0289). RetroPie is rescraped at 427e762: the three
passes_path records are its only change.

advmame, advmame-1.4 and advmame-0.94 carry a retropie config_reads
for dir_rom, read at the build RetroPie installs (96237a5, the tag
advancemame-1.4 its tarball matches, the 0.94.0 tarball). The 1.4 and
0.94 profiles gain the dir_rom pool and a path for each set, and 0.94
a pin_build on rp_module_repo.

Manifests: on RetroPie 55 sets of the three builds move from the BIOS
root to roms/mame-advmame, the first folder of the list, which every
game started from either folder reads. Seven archives other cores
share stay at the root for them. No other platform changes. verify
--all keeps its severity and status counts.
