[Ext/Filter/Meson/EdgeTPU] Add build_rpath when test is enabled

In order to provide the proper location of the test helper library which
mocks edgetpu.so, this patch adds build_rpath to the shared_object
statement in the meson build script for the edgeTPU filter extensions
when 'enable-test' is true.
