bootstrap: accept --gnulib-srcdir=/path/to/gnulib again.

During the split of bootstrap into options-parser and
extract-trace, the generic long-option splitting code got lost.
* libltdl/config/options-parser (func_parse_options): Add the
code to split any long option separated by an equals from its
optarg back in.
