wks: Fix filter expression syntax flaw.
* tools/wks-util.c (wks_get_key, wks_filter_uid): The filter expression needs a space before the value. (install_key_from_spec_file): Replace es_getline by es_read_line and remove debug output.
A value of starting with '<' was considered an invalid operator due to
our tokenization method.
