Fix Windows packaging step: simplify bash { } | sort -u | while pattern

The previous step used a bash group command piped through sort -u and a
while loop. Under MSYS2 bash + 'set -e -o pipefail' (GitHub Actions
default), this triggered a non-zero exit even when the loop body
succeeded, causing the Windows daemon job to fail at the packaging step
(the actual link of both trianglesd.exe and triangles-cli.exe succeeded).

Replaced the { } | sort -u | while pattern with a temp-file-based dedup:
- ldd both binaries, append to /tmp/cli-dlls.txt (or cli-libs.txt on Linux)
- sort -u the temp file
- pipe the result into the while loop (simpler pipeline, no group)

Also applied the same simplification to the Linux .deb packaging for
consistency, even though the Linux build was passing.
