bug#15353: [PATCH 12/19] tests: rewrite t6001 to use /dev/mapper

[Brian C. Lane]

From: "Brian C. Lane" <address@hidden>

This test began failing because using a private copy of /dev/mapper
confuses the system. This fixes that and generally cleans up the test.

tests/t6001.sh: update to use /dev/mapper directly
