Make odin Linux release builds usable on normal systems.

# The Odin binary package is built on Ubuntu, which inherits Debian's
# libedit stupdity.  This makes the binary builds unusable, but it
# is easy to fix with patchelf to change the dependency to what normal
# systems ship.

# See: https://salsa.debian.org/debian/libedit/-/blob/master/debian/patches/update-soname.diff

It appears that you are running Debian or a derivative such as Ubuntu.

There should be no fixes to shared libraries required, as Ubuntu is used
to build the Odin release packages.
