qemu: fix a build race condition

qemu will depend on pam if libpam is present. However, there is a
time-of-check to time-of-use issue in meson, qemu's build system. Meson
will hardcode the exact location and version of libpam at configure
time. If libpam is reinstalled sometime after configure and before
build, the recorded location and version of libpam may be invalid at
build time and the qemu build will fail. We can address this by listing
pam as a dependency of qemu, meaning that pam will be installed before
qemu if they appear in the same depgraph.

This change is already upstream:
https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=4da484b352e21676d7e0b13c5aa54db2a69c8271
so we will not regress when we upgrade qemu.
