As of commit 076b35b5 (machine: add default_ram_size to machine
class) we no longer have a global default ram size, but instead
machine specific defaults.  When invoking qemu --help we don't know
which machine you selected, so we can't tell the user the default RAM
size in the help text anymore now.

Thus I don't see an easy way to expose the default ram size to the
user in the help text.  The easiest option IMHO is to just drop this
piece of information.
