[OE-core][PATCH v2] libyaml: add ptest support

[Pratik Farkase <pratik.farkase@est.tech>]

Add ptest support for libyaml to enable running the test suite
on target devices. This includes:

- test-version: Verifies library version information
- test-reader: Tests YAML reading functionality

All 2 upstream tests pass successfully:
START: ptest-runner
BEGIN: /usr/lib/libyaml/ptest
PASS: test-version
PASS: test-reader
DURATION: 0
END: /usr/lib/libyaml/ptest
STOP: ptest-runner

Changes in v2:
- Remove hardcoded version from test summary
- Remove static XFAIL/XPASS/ERROR lines (always 0)
- Move PTEST_TESTS definition above functions for better readability
- Auto-discover test binaries in run-ptest
