[Linux] Cache files in $XDG_CACHE_HOME/tldr instead of ~/.tldr_cache

[chocolateboy]

According to the XDG Base Directory Specification, user-specific cached files files should be stored in $XDG_CACHE_HOME/tldr, or $HOME/.cache/tldr if $XDG_CACHE_HOME is not defined.

There is a single base directory relative to which user-specific non-essential (cached) data should be written. This directory is defined by the environment variable $XDG_CACHE_HOME.

This avoids cluttering the home directory and simplifies including/excluding related directories from bulk operations such as backups.
