restore support for --defaults-file=<(...)

if my_realpath() fails, don't return the error code, get_defaults_options()
returns a number of options consumed, not 0=ok/1=error.

instead, ignore the error from my_realpath. If it fails it internally
falls back to my_load_path, which restores 10.4- behavior
