libucontext: Bring in mips/mips64 support

License-Update: Updated copyright years [1]

Latest master 0.10.x+ has added support for mips/mips64, which should
help compile ruby on musl for these architectures

Switch SRC_URI to github upstream URI

Check for common arches before checking others in map_kernel_arch

Drop already upstreamed patches
