[PATCH 2/2] ftrace/selftest: absence of modules/programs should trigger unsupported errors

[Alan Maguire <alan.maguire@oracle.com>]

In a number of cases, the ftrace tests check for the presence of
ftrace testing-related modules (ftrace-direct, trace-printk) and
programs (checkbashisms), returning exit_unresolved if these
are not found.  The problem is, exit_unresolved causes execution
of ftracetest to return an error, when really our tests are
failing due to not having the requisite kernel configuration/tools
present, which is I think more of an unsupported error condition.
With these fixed, we see no unresolved test cases and ftracetest
returns success ("ok" when run via kselftest).

Fixes: 646f01ccdd59 ("ftrace/selftest: Add tests to test register_ftrace_direct()")
Fixes: 4d23e9b4fd2e ("selftests/ftrace: Add trace_printk sample module test")
Fixes: 7bc026d6c032 ("selftests/ftrace: Add function filter on module testcase")
Fixes: ff431b1390cb ("selftests/ftrace: Add a test to probe module functions")
Fixes: 4a075bd4e13f ("selftests/ftrace: Add checkbashisms meta-testcase")
