fix(plymouth): check all library directories for Plymouth

On amd64 `dpkg-architecture -qDEB_HOST_MULTIARCH` returns
`x86_64-linux-gnu` but `uname -m` returns only `x86_64`.
`/usr/lib/x86_64` does not exist on Debian/Ubuntu but
`/usr/lib/x86_64-linux-gnu` exists.

Rely on `libdirs` to provide all possible library directories including
the Debian multiarch directory `/usr/lib/x86_64-linux-gnu`.

Fixes: 1b374931126c ("fix(plymouth): do not depend on dpkg-architecture")
