Richard Purdie 7cb670c4a9 qemu: Drop vm reservation changes to resolve build issues
When building with the new version of qemu we see errors like:

"""
qemu-i386: Unable to reserve 0x7ffff000 bytes of virtual address space at
0x1000 (Success) for use as guest address space (check your virtual memory
ulimit setting, min_mmap_addr or reserve less using -R option)

ERROR: The postinstall intercept hook 'update_gio_module_cache-nativesdk' failed
"""

The VM reseration patches we're carrying look suspicious in this context.
Drop them since the patches appear to be a liability causing other issues
and there is a much  simpler fix for the webkitgtk issues on musl on
32 bit (see later linux-user mmap patches).

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
