[PATCH] testsuites/fstests/dos: Fix format truncation warning

[Aschref Ben-Thabet]

From: Aschref Ben Thabet <aschref.ben-thabet at embedded-brains.de>

Replace the snprintf() code line with memcpy() and strcpy(). First copy
the MOUNT_DIR to dirname and add the '/' character, then copy the
invalide directory name.
