strata 0.20.1, flea 0.3.4, owe 0.2.7: fix check() on the builders

strata: the example actions' image test needs ImageMagick with WebP
(checkdepends), the checksum example dies printing a non-UTF-8 name
under the builder's en_US.UTF-8 locale (upstream bug, skipped), and on
aarch64 a search refresh test loses a race to the index worker.

flea: on aarch64 the 1900-deep dirsize walk hits its 2 s deadline, and a
process-group cancel test loses its 5 s race under emulation.

owe: on aarch64 the transition test cannot render enough blended frames
under emulation; run every other test there.

Versions and checksums as in sync PR #660.
