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.
