[PATCH stalld 06/36] tests/functional: Fix test_logging_destinations.sh path and backend

Tests 1 and 4 invoke stalld directly to capture its stdout for
verification. They used a relative path (../stalld) that breaks
when run_tests.sh invokes the test from a different working
directory, and used pgrep to find the PID instead of capturing $!
from the background launch. They also lacked backend passthrough
for matrix testing.

Fix the stalld path to use ${TEST_ROOT}, capture the PID via $!,
add BACKEND_FLAG construction and passthrough for the direct
invocations, and remove a redundant rm -f already handled by
CLEANUP_FILES. Tests 2 and 3 use start_stalld and need no changes.
