[jhbuild] make: use symbolic link name if inside one

[Michael Catanzaro <mcatanzaro src gnome org>]

    make: use symbolic link name if inside one
    
    os.getcwd() returns the absolute path. Using that causes the 'make'
    command fail when the module directory is inside a symlink directory.
    
    This patch gets the path from 'PWD' env variable value which won't
    translate the symbolic path to absolute path. Also fallback to
    os.getcwd() in case 'PWD' isn't present.
