util-linux: fix CVE-2022-0563
A flaw was found in the util-linux chfn and chsh utilities when compiled
with Readline support. The Readline library uses an "INPUTRC" environment
variable to get a path to the library config file. When the library cannot
parse the specified file, it prints an error message containing data from
the file. This flaw allows an unprivileged user to read root-owned files,
potentially leading to privilege escalation. This flaw affects util-linux
versions prior to 2.37.4.
Backport patch from upstream:
https://github.com/util-linux/util-linux/commit/faa5a3a83ad0cb5e2c303edbfd8cd823c9d94c17
Patch required slight modifications to apply cleanly to util-linux 2.35.1
