package/dracut: fix dracut_wrapper
As reported by Thierry Bultel [1], dracut doesn't work since the
version bump to version 059.
Further investigation by Andreas Naumann [2] reported that the issue
come from this commit d010fa0 refactor(dracut-install): fork() instead
of popen(), sanitise line reading [3].
The issue come from our dracut_wrapper and how DRACUT_LDD is defined.
Indeed dracut expect DRACUT_LDD=ldd or a single binary (without
arguments) but we are using "prelink-rtld --root='${sysroot}'".
With the change introduced by [3], our DRACUT_LDD is used
directly by execlp() leading to an error:
execlp(ldd, ldd, fullsrcpath, (char *)NULL);
Use mktemp to generate a temporary dracut-ldd script using
prelink-rtld --root='${sysroot}' ${1}
execute dracut.real in a subshell to cleanup the temporary file
at the end of the dracut wrapper script.
