Tests fail to compile with pre-release glibc and leatherman-vendored Catch about cpp-hocon

[musicinmybrain]

My existing patch is a quick and dirty unconditional one:

# Do not use the obsolete vendored copy of the Catch unit testing library
# included with leatherman.
sed -r -i 's/(LEATHERMAN_COMPONENTS)(\b.+)?(\bcatch\b)/\1\2/' CMakeLists.txt
sed -r -i 's|\$\{LEATHERMAN_CATCH_INCLUDE\}|"%{_includedir}/catch"|' \
    lib/tests/CMakeLists.txt

If I have a chance to write a clean version with a boolean, and without platform-dependent assumptions, I will submit a PR and link it here. It won’t be right away but it might be sooner than a few weeks.

This seems like something we should fix. I'm happy to accept a patch if you have one for setting up a boolean to use system Catch. Otherwise this may take a few weeks before I can get to it.

FWIW: glibc-2.34 was released in August.
