topshim/facade: Don't link with libbluetooth twice

libbluetooth was linked statically and dynamically causing a lot of
issue because of duplicated instances, to fix that we only link
with libbluetooth statically.

Linking statically with libluetooth is not straightforward because
of the dependency with bt_shim that depends on rust crates that
are used by bt_topshim_facade too, leading to linking twice with
theses libs and so the linker complaining of duplicate symbols.

To fix that we instead pass bt_shim as dependency of bt_topshim_facade
so the rust compiler will take care of only including the transitive
dependencies once

Test: m bt_topshim_facade
Test: out/host/linux-x86/bin/bt_topshim_facade
