fix: Reduce verbosity if version file is missing

As we don't check for the existance of the version file this would
otherwise emit a useless error to the commandline:

    > ==> Building protobuf for [extra-staging] (x86_64)
    > cat: /var/lib/archbuild/extra-staging-x86_64/root/.arch-chroot: No such file or directory
    > ==> Creating chroot for [extra-staging] (x86_64)...

Fix this by just silencing the error, as the check later also covers the
case for empty `CURRENT_CHROOT_VERSION`.

Fixes #272
