Subject: utils: Avoid need to relocate wrapper scripts

Whilst the path to the executable is dynamically determined, the passed in
environment variables or parameters are not relocatable and rely on the sstate
remapping code. In the recipe specific sysroot case this has become more costly.

This patch translates such paths into relocatable entries which means that
a sed replacement at final installation isn't needed.
