build: support variant builds via env-var and cpack overrides #40947

Problem: scripts/genappimage.sh runs `make` with no extra flags and
emits a fixed nvim-linux-<arch>.appimage filename, so packaging a
variant build (e.g. with the bundled PUC-Rio Lua interpreter)
requires editing the Makefile or post-renaming the AppImage, which
breaks the AppImage zsync URL.

Solution: forward DEPS_CMAKE_FLAGS and CMAKE_EXTRA_FLAGS to `make`,
accept OUTPUT so the AppImage (and its zsync Filename:) follows the
caller's chosen name, and mark CPACK_PACKAGE_FILE_NAME as CACHE
STRING on Linux so the resulting tarball/deb follow as well. Default
behavior is unchanged when none of these env vars are set.
