No, since x86-64-linux-gnu is not a standard name for the architecture.  I
would suggest that you instead simply use the dh-exec substitution for the
first part of the path, and a glob for the second:

  usr/lib/${DEB_HOST_MULTIARCH}/libpytalloc-util.cpython-37m-*.so.*

That should minimize any false-positive matches of the glob.
