linux-user: improve fake /proc/self/stat making `ps` not segfault.

With the current fake /proc/self/stat implementation `ps` is
segfaulting because it expects to read PID and argv[0] as first and
second field respectively, with the latter being enclosed between
backets.

Reproducing is as easy as running: `ps` inside qemu-user chroot
with /proc mounted.

linux-user: fail execve() if env/args too big

If the host's page size is equal to or smaller than the target's, native
execve() will fail appropriately with E2BIG if called with too big an
environment for the target to handle. It may falsely succeed, however, if
the host's page size is bigger, and feed the executed target process an
environment that is too big for it to handle, at which point QEMU barfs and
exits, confusing procmail's autoconf script and causing the build to fail.

This patch makes sure that execve() will return E2BIG if the environment is
too large for the target.

linux-user: fix wait* syscall status returns

When calling wait4 or waitpid with a status pointer and WNOHANG, the
syscall can potentially not modify the status pointer input. Now if we
have guest code like:

int status = 0;
waitpid(pid, &status, WNOHANG);
if (status)
<breakage>

then we have to make sure that in case status did not change we actually
return the guest's initialized status variable instead of our own uninitialized.
We fail to do so today, as we proxy everything through an uninitialized status
variable which for me ended up always containing the last error code.

This patch fixes some test cases when building yast2-core in OBS for ARM.
