From: Virendra Thakur <virendra.thakur@kpit.com>

During ptest execution, util-linux adds mount entries in /etc/fstab
and runs `mount -a`, which mounts all available entries from
/etc/fstab. This can cause unintended mounts that are unrelated to
the test, leading to incorrect test behavior.

To avoid this, upstream util-linux introduced a mechanism using
CUSTOM_FSTAB,which isolates test-specific fstab entries. Only entries
listed in CUSTOM_FSTAB are mounted during test execution, ensuring
tests do not interfere with or depend on the system's /etc/fstab.

This commit backports below upstream changes to use CUSTOM_FSTAB.
