Fix rctemplate tests when user config file exists.

QuLogic · QuLogic · commit 1c934f024f4c · 2018-03-31T01:33:10.000-04:00
`matplotlib_fname` returns the first of user config, environment
variable-specified config, or default system config. If the user has a
matplotlibrc, then this test checks that instead of the system one.
