Add ptest support to enable automated testing of libconfig
using ptest-runner.

The implementation uses libtool --mode=install to properly
install test binaries, avoiding issues with libtool wrapper
scripts. Tests are built via 'make check TESTS=' to compile
without running during the build phase.

The test suite includes 16 tests covering parsing, formatting,
binary/hex values, escaped strings, and various edge cases.
All tests pass successfully on qemux86-64 :
