Split normal memfd and hugetlbfs tests to improve the test reporting.
Remove run_fuse_test.sh and memfd_test from run_tests.sh and add them
to the Makefile.
Add memfd_test to TEST_GEN_PROGS to be run separately.
Rename run_tests.sh to run_hugetlbfs_test.sh
Add run_fuse_test.sh and run_hugetlbfs_test.sh to TEST_PROGS
The report for non-root run wth this change is:

When memfd test is skipped because of unmet dependencies and/or unsupported
configuration, it returns non-zero value which is treated as a fail by the
Kselftest framework. This leads to false negative result even when the test
could not be run.
Change it to return kselftest skip code when a test gets skipped to clearly
report that the test could not be run.
Added an explicit check for root user at the start of memfd hugetlbfs test
and return skip code if a non-root user attempts to run it.
In addition, return skip code when not enough huge pages are available to
run the test.
Kselftest framework SKIP code is 4 and the framework prints appropriate
messages to indicate that the test is skipped.

With the addition of hugetlbfs support in memfd_create, the memfd
selftests should verify correct functionality with hugetlbfs.
Instead of writing a separate memfd hugetlbfs test, modify the
memfd_test program to take an optional argument 'hugetlbfs'. If the
hugetlbfs argument is specified, basic memfd_create functionality will
be exercised on hugetlbfs. If hugetlbfs is not specified, the current
functionality of the test is unchanged.
Note that many of the tests in memfd_test test file sealing operations.
hugetlbfs does not support file sealing, therefore for hugetlbfs all
sealing related tests are skipped.
In order to test on hugetlbfs, there needs to be preallocated huge
pages. A new script (run_tests) is added. This script will first run
the existing memfd_create tests. It will then, attempt to allocate the
required number of huge pages before running the hugetlbfs test. At the
end of testing, it will release any huge pages allocated for testing
purposes.
