Add Fossil 1.29 recipe and patch
* This builds cleanly for x86_gcc2, x86, and x86_64
* The patch fixes a zlib namespace clash with OpenSSL that affects x86_gcc2, as well as an outdated config.guess which prevented Haiku x86_64 from being identified
* The 1.29 release will allow `fossil ui` to work correctly, unlike the last couple of versions that had a chroot bug that affected OS's like Haiku that run as root out of the box
