Fix problem with FC2's vdso (sysinfo) page, which lives at a low,

random address.  This gets unmapped as part of the client setup, and
causes syscalls to fail as a result.  This patch simply disregards the
sysinfo page.  It seems like a blunt fix, but I don't think anything
depends on a sysinfo page.
