ecp5: cmake: Search for pytrellis.so in multiple locations

Browse Source 
If a distro-specific "trellis-devel" package is used, the
pytrellis.so library might be located in a dedicated directory,
rather than under TRELLIS_ROOT.

Search for pytrellis.so in a list of directories, then subsequently
use the first match as part of PYTHONPATH.
