[PATCH RESEND v2 01/12] selftests/mm: mremap_test: remove command line options

[Sarthak Sharma <sarthak.sharma@arm.com>]

mremap_test supports command line options for changing
the validation threshold and random pattern seed.

As part of a larger series to remove validation threshold
and randomization, remove all command line options from
the test. The test is already invoked without any
arguments in run_vmtests.sh, so no runner changes are
required.
