[PATCH 3/4] Fix 'make check' in utils

[Jon Turney]

This has a test of the path translation code used in various
utilities (mount, cygpath, strace).

MOUNT_BINARY is replaced with the absence of MOUNT_TEXT since 26e0b37e.
The isys member of mnt_t struct was removed in b677a99b.

> fail       : 0 (0.0%)
