The payload pinned libc++ 29 while the build container's apt cmake needs 30,
so the two disagreed and the shim in the previous commit papered over it. The
pool has since retired 17 of our pins, so repin them all with
`hermes pm update --termux`, which fixes the mismatch at the source.
Repinned: libc++ 29 -> 30 plus 14 more runtime libs (fribidi, glib, harfbuzz,
libaom, libbluray, libexpat, libheif, libmp3lame, libpng, libvidstab, openssl,
pcre2, readline, vulkan-loader-generic) and the bionic lock rows for uv
0.12.15 -> 0.12.23 and ffmpeg 8.1.2-5 -> 8.1.3. The pool serves ffmpeg 8.1.3
only, so that row moves back from 9.0.1 as the pool has it.
Staging with the new table succeeds: 84 packages, 269 .so, same counts as
before. The libc++ SONAME is unchanged. The one unresolved DT_NEEDED
(libharfbuzz-cairo -> libcairo) is present on the old table too.
The shim is removed. What stays from it is the in-container
`cmake -E capabilities` check, which fails in 2 minutes if the table drifts
from the pool again, instead of after 30 minutes of compiling.
