wipe-sysroot: fix removals

The previous changes were totally broken as quoting globs doesn't work.  Remove
the quotes so the rm commands actually delete the stamps.

runqemu: set memory size to 256M for most qemu machines

Set memory size to 256M for qemuarm, qemux86, qemux86-64, qemumips,
qemumips64, and qemuppc.

This allows the smart automated tests to run on machines with a GUI
environment (such as Sato) running at the same time, for which 128M is
too limiting. Setting this in runqemu allows users manually using
runqemu to avoid the same out-of-memory issues under similar conditions
using smart, on-target compilation or other uses.

Fixes [YOCTO #5045].

elfutils: Drop do_autoreconf patches

The do-autoreconf patches only change generated files. We run autoreconf ourselves
so we don't need these patches. Worse, they cause failures since the do_patch
task can't rerun after configure since the files change and the patch is no longer
clean.

Drop the patches since we don't need them.
