[PATCH] rust: workaround compilation failures with Meson <1.10

[PATCH] rust: workaround compilation failures with Meson <1.10

[Paolo Bonzini]

Prior to Meson 1.10, if the config-host.h dependency of qemuutil ends up
as the first source file, it can be passed to rustc---which gets rather
confused because config-host.h looks nothing like Rust code.

While this can usually be avoided in the individual targets, a simple
and universal workaround is to remove the sources (and C compile
arguments, while at it) from the "util_rs" dependency.  This hides
config-host.h from the Rust targets---and they don't need it anyway.
