selftests/bpf: Fix test_progs-flavor run getting number of tests
Commit 643e7233aa94 ("selftests/bpf: Test_progs option for getting number of
tests") introduced ability to getting number of tests, which is targeted
towards scripting. As demonstrate in the commit the number can be use as a
shell variable for further scripting.
The test_progs program support "flavor", which is detected by the binary
have a "-flavor" in the executable name. One example is test_progs-no_alu32,
which load bpf-progs compiled with disabled alu32, located in dir 'no_alu32/'.
The problem is that invoking a "flavor" binary prints to stdout e.g.:
"Switching to flavor 'no_alu32' subdirectory..."
Thus, intermixing with the number of tests, making it unusable for scripting.
Fix the issue by only printing "flavor" info when verbose -v option is used.
