This commit adds an "Extract to subdirectory" option to
the extract dialog which allows the user to extract the
contents of the archive to a directory with the name of
the archive (without the extension.) The user will be
prompted if the directory must be created.

file-utils.c: Improve remove_extension_from_path

Rework this function so that it correctly parses and
truncates files with multiple extensions like .tar.gz

file-utils.c: Improve get_file_extension

Improve this function to correctly identify and return
supported compressed tar file extensions

The application/gzip alias is e.g. provided by FileRoller and Ark,
application/bzip2 is provided by FileRoller.

As of it's now, we're supporting zstd {,de}compression with specific
mime type that was reported by libmagic as configure time. Thus, the
built binaries is not correct after upgrading file-devel after
configure. In addition, this configure's time hard-coded value prevent
our users from partial upgrade.

Let's accept both mime types reported by both old and new file-devel.
For the mapping between file extensions and mime types, let's choose the
new mime value.
