sdk: invoke bundle-libraries.sh w/o buildroot dirs in $PATH

Invoke bundle-libraries.sh with any buildroot related directory entries
removed from $PATH to avoid picking up cross versions of utilities like
ldd which will not properly work when used against host executables.

This should fix executable bundling for glibc-target SDKs.
