Do not assume FHS in init-repository and configure

On systems that do not follow the Filesystem Hierarchy Standard, such as
guix, the hardcoded `/bin/pwd` will fail to be found so that the script
will fail.

Use `pwd`, instead, so that the command can be found through the normal
path search mechanism.
