tests: Disable the migrations tests

* tests/Makefile.am (SUBDIRS): Remove migrations.
* configure.ac (AC_CONFIG_FILES): Remove migrations Makefile.
--

The tests introduced with commit defbc70b require some non-portable
tools like mktemp and basename.  They further fail with "make
distcheck".  Removed for now.
