gnu: timescaledb: Adjust test preparation to PostgreSQL 13.6.

Browse source 
The previous method of making a union with symlinks would work with 13.4
but not with 13.6, which has an extra 'canonicalize_path' call in
'find_my_exec'.

* gnu/packages/databases.scm (timescaledb)[arguments]: In
'prepare-tests', pass #:symlink argument to 'union-build'.
