First 2.5 build got past the deb install but the binary-discovery step
produced an empty $BIN (test -n failed): the 2.5 deb names its executable
casparcg-server-2.5, which the old case pattern (*/casparcg, */CasparCG
Server) didn't match. Broaden the match to /usr/bin/*casparcg*server*, fall
back to the known /usr/bin/casparcg-server-2.5, symlink it to
/usr/local/bin/casparcg, and make /opt/casparcg a real dir for our config
(no longer symlinked onto /usr/bin). Entrypoint launches `casparcg <config>`
from PATH instead of ./casparcg in a cwd.
Still NOT runtime-validated: 2.5 may reject the 2.3-era casparcg.config
schema (a bad config shows up as "Configuration file --version was not
found"); the deb ships a reference config at
/usr/share/casparcg-server-2.5/casparcg.config to diff against at smoke time.
