    package: fix source tree check for the jhbuild-in-$HOME case
    
    Previously we were generically checking if the binary was launched
    somewhere from '.', under the assumption that packages are installed
    in /usr or /opt, so invocations like './.../' are only for uninstalled.
    This breaks if one configures jhbuild to install somewhere in the
    home directory, so instead we should check for ./src/$pkgname explicitly.
    In any case, running './program' from src/ would not work anyway,
    as the other relative paths would be wrong.
