[LTP] [PATCH v2] quota_remount_test01: Add explicit check for dependencies

[Punit Agrawal <punit.agrawal@arm.com>]

quota_remount_test01 doesn't check for dependencies before
execution. Add explicit checks for quotacheck and quotaon and bail out
if they are not present.

Signed-off-by: Punit Agrawal <punit.agrawal@arm.com>

v2:
* Replaced the use of test.sh with shell commands to check for test
  dependencies
