John Ericson e941b031d3 Revert "[cmake] Use CMAKE_INSTALL_LIBDIR too"

Unfortunately this causes a number of failures that didn't show up in my
local build.

# Mimick `GNUInstallDirs` for one more install directory, the one where
# project's installed cmake subdirs go.
# These functions are internal functions vendored in from GNUInstallDirs (with
# new names), so we don't depend on unstable implementation details. They are
# also simplified to only handle the cases we need.
#
# The purpose would appear to be making `CACHE PATH` vars in a way that
# bypasses the legacy oddity that `-D<PATH>` gets canonicalized, despite
# non-canonical `CACHE PATH`s being perfectly valid.
