[PRQ#58519] Merge Request for dahdi

MarsSeed [1] filed a request to merge dahdi [2] into dahdi-linux [3]: Renaming to more correct pkgname. The target name is upstream's name, and it is also tied to the specific Arch Linux kernel. There is already a dahdi-linux-git pkg as well. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/dahdi/ [3] https://aur.archlinux.org/pkgbase/dahdi-linux/
