Tracking issue of temp/ packages

We should really try to decrease the number of packages we have in temp/, so I've looked at them and why we have them.

Out of the 13 packages we have there, I know of only 2 packages that have an open pull request to the Alpine aports.

• dhcpcd: disable IFA_F_NOPREFIXROUTE (for old kernels)
• gpgme: build qgpgme upstreamed
• jemalloc: was dropped in Alpine, we build temp/qemu against it
• libdrm: newer version (etnaviv and tegra) upstreamed
• libical: build fix (https://github.com/alpinelinux/aports/pull/6986)
• lightdm
• lttng-tools: newer version (https://github.com/alpinelinux/aports/pull/5319 / https://patchwork.alpinelinux.org/patch/4693/) not used anymore - removed from pmaports
• mesa: newer version Replaced by mesa-git
• mesa-freedreno: device-specific package The devices that used this now use mesa-git
• mesa-purism-gc7000: device-specific package
• qemu: build against jemalloc - work around a deadlock while compiling mesa
• qt5-qtbase: Use OpenGL ES2
• qt5-qtdeclarative: Compile for armv7 - see postmarketOS/pmaports#75, also needed for GLES (#270 (closed))
• qt5-qtwayland: Patches that fix a ton of crashes
• u-boot: build for pine64
• weston: ABGR patch (https://github.com/alpinelinux/aports/pull/7079)
• wlroots: elogind support & rootston binary
• xkeyboard-config: Add N900 extended layout
• u-boot-librem5dev: device-specific package
• mesa-grate: device-specific package to build the grate driver
• libdrm-grate: device-specific package to build the grate driver
