feat: profile RetroPie's AdvanceMAME tip build

RetroPie clones amadvance/advancemame at the branch tip with no
revision (scriptmodules/emulators/advmame.sh:16, 39-41 at 427e762), so
advmame is profiled at 96237a5 (v5.0-484), built_by retropie and held
by pin_follows. RetroPie's advmame now resolves to it, advancemame
keeping EmuELEC, AmberELEC and Recalbox.

The MAME workflow at 96237a5: 28 BIOS roots registered in
mame/mamedriv.c (macs2bios is not), the eight ZN roots under their MAME
names (coh1000c, coh3002c, coh1002m, coh1000t, coh1002e, coh1001l,
coh1000w, coh1000a), modern Neo Geo members, coh1000w's CAT702, and 15
device archives that BIOS_LOAD reads first (atarisy1, coh3002t, m1comm,
midssio, namcoc65/68/69/71/74, s_smp, saa5050, sente6vb, sns_dsp1bleg,
t5182, v4bios). bctvidbs declares no ROM of its own. Three laserdisc
player programs are opened by name outside any ROM list, with a fatal
length, CRC32 and SHA1 check: pr8210, 22vp931 and simutrek.

pin_build accepts pin_follows in the schema, and bump_commit advances a
built_by profile that follows the tip.

Manifests: RetroPie gains 24 archives at its BIOS root, the ZN ones
under their new names, and nss.zip moves to the copy holding
nss-c.dat and nss-ic14.02. The other platforms do not change.
verify --all keeps its counts. profile_sync: 0 to review.
