runqemu: Stop passing bindir to the runqemu-ifup call

runqemu: Stop passing bindir to the runqemu-ifup call

Since https://git.yoctoproject.org/poky/commit/?id=51063c1e6ac
we need to pass exactly 2 arguments to runqemu-ifup, otherwise
the script will return an error since bindir is no longer being
used.

However the call to runqemu-ifup from runqemu is still passing
bindir as an argument resulting in the error mentioned above,
remove the bindir argument to fix this issue.
