CMakeDetermineCompilerABI: Revert "Parse library arch from versioned paths"

The change in commit 657fc3a9a7 (CMakeDetermineCompilerABI: Parse
library arch from versioned paths, 2021-02-03, v3.20.0-rc1~40^2) caused
`CMAKE_LIBRARY_ARCHITECTURE` to be populated on non-multiarch platforms
if their compilers happen to use `$arch/$version` library directories.
Revert the use of versioned library paths.

Fixes: #22024
