test_parse_test_list_file writes some data to
/tmp/bpf_arg_parsing_test.XXXXXX and parse_test_list_file() will read
the data back. However, after writing data to that file, we forget to
call fsync() and it's causing testing failure in my laptop. This patch
helps fix it by adding the missing fsync() call.

We started getting a crash in BPF CI, which seems to originate from
test_parse_test_list_file() test and is happening at this line:
ASSERT_OK(strcmp("test_with_spaces", set.tests[0].name), "test 0 name");
One way we can crash there is if set.cnt zero, which is checked for with
ASSERT_EQ() above, but we proceed after this regardless of the outcome.
Instead of crashing, we should bail out with test failure early.
Similarly, if parse_test_list_file() fails, we shouldn't be even looking
at set, so bail even earlier if ASSERT_OK() fails.

Improve test selection logic when using -a/-b/-d/-t options.
The list of tests to include or exclude can now be read from a file,
specified as @<filename>.
The file contains one name (or wildcard pattern) per line, and
comments beginning with # are ignored.
These options can be passed multiple times to read more than one file.

Split the logic to insert new tests into test filter sets out from
parse_test_list.
Fix the subtest insertion logic to reuse an existing top-level test
filter, which prevents the creation of duplicate top-level test filters
each with a single subtest.

Improve subtest selection logic when using -t/-a/-d parameters.
In particular, more than one subtest can be specified or a
combination of tests / subtests.
-a send_signal -d send_signal/send_signal_nmi* - runs send_signal
test without nmi tests
-a send_signal/send_signal_nmi*,find_vma - runs two send_signal
subtests and find_vma test
-a 'send_signal*' -a find_vma -d send_signal/send_signal_nmi* -
runs 2 send_signal test and find_vma test. Disables two send_signal
nmi subtests
-t send_signal -t find_vma - runs two *send_signal* tests and one
*find_vma* test
This will allow us to have granular control over which subtests
to disable in the CI system instead of disabling whole tests.
Also, add new selftest to avoid possible regression when
changing prog_test test name selection logic.
