Use less-generic names in matview.sql. 

The original coding of this test used table and view names like "t",
"tv", "foo", etc.  This tended to interfere with doing simple manual
tests in the regression database; not to mention that it posed a
considerable risk of conflict with other regression test scripts.
Prefix these names with "mvtest_" to avoid such conflicts.

Also, change transiently-created role name to be "regress_xxx" per
discussions about being careful with regression-test role creation.
