Fix fakeroot and remap parsing corner cases
Fix case when $PWD contains spaces. Pass directly arguments to command, to directly avoid escaping issues. Based on suggestion by Ivan Shmakov <oneingray@gmail.com> * utils/fakeroot.sh (TARGET): Do not define. (sh): Rather pass PWD and commandline as parameters. * utils/remap.sh: Likewise.
