build: add argument to specify build directory to deploy

This commit modifies the script
`deploy/build_env/services-linux/run_asapo.sh` so that we can use it
to deploy services compiled in a directory other than `build/`. This is
very convenient during development on a local machine  because we may
want to store different build flavors in directories under the `build/`
directory.

Note: if no directory is passed to the script, the script uses the
`build/` directory by default.
