    libcharset: Drop a redundant environment variable
    
    It was used for running tests when we built with autotools, but is no
    longer used in the Meson build system. If we need something similar in
    future, it should be done by adding internal API to override the
    directory on a per-call basis, rather than loading a path from a shared
    global table every time.
