configure: substantially de-bong libpng handling

- remove --unix-qstart-libpng:
the internal libpng is static lib so this option is pointless
- clean up duplicative libpng checks
- replace usage of ENABLE_QUICKSTART_LIBPNG with ENABLE_HEADLESS,
which is the one case where it could still be disabled
