Subject: use fixed data dir instead of determining it at runtime
From: Michael Tokarev <mjt@tls.msk.ru>
Debian-specific: yes

Since we install to a fixed location, use fixed data directory
instead of deriving it at runtime from executable path.
This way it is possible to move qemu binary to another directory
and it will still work.
