Movies play: answer the CPU ~MHz registry value, turn movies on by default

The game decodes VP6 itself.  The first movie hung because the movie timer
(sub_006f625d) reads HKLM\...\CentralProcessor\0 "~MHz" and, without it,
calibrates RDTSC against QueryPerformanceCounter until two measurements agree.
QPC is our virtual clock and RDTSC real time, so they never agreed.  Answering
3000 (rdtsc_shim's rate) skips the calibration; the logos, the PSA and the
opening movie play with sound on the original and HD engines.

The app and run.sh now default to NOMOVIES=0; tools/check.sh keeps
NOMOVIES=1 for repeatable runs.
