Alex Vanderveen 2298c90cb7 rewind: do not densify the FMV capture interval at 8 MB

An 8 MB snapshot is ~10 MiB raw and do_capture streams its deflate at
RW_ZSLICE (1 MiB) per vblank, so one capture takes ~10 vblanks to drain
and any capture requested while s_zpend is active is skipped. Asking for
a capture every 4 frames therefore never achieves 4 — it just pins the
compressor at 100% duty on the emu thread for the whole movie, buying
rewind granularity the pump cannot actually deliver.

Measured on the WipEout 3 ntscfull8 intro: 17% of FMV frame rate.

Give the FMV interval the same 8 MB floor RW_DEF_INTERVAL_8MB already
gives the normal one. PSX_REWIND_FMV_INTERVAL still overrides (its clamp
grows to 60 so the new default is reachable).
