[PATCH v2 4/6] docs/about/deprecated: Deprecate the qemu-system-arm binary

[Thomas Huth <thuth@xxxxxxxxxx>]

qemu-system-aarch64 is a proper superset of qemu-system-arm,
and the latter was mainly still required for 32-bit KVM support.
But this 32-bit KVM arm support has been dropped in the Linux
kernel a couple of years ago already, so we don't really need
qemu-system-arm anymore, thus deprecated it now.
