gnu: ecryptfs-utils: Wrap scripts.

This should fix #59850, although there might be other binaries I missed.

* gnu/packages/linux.scm (ecryptfs-utils)[arguments]: Add a new
'wrap-scripts phase to do what it says.
[inputs]: Add coreutils, findutils, gawk, grep, keyutils, lsof, rsync,
sed, and which.
