[RFA 1/2] Remove cli_ui_out::out_field_fmt

[Tom Tromey]

I noticed that cli_ui_out::out_field_fmt is only used by a single
caller, and it can easily be replaced by fputs_filtered.  So, this
patch removes it.

ChangeLog
2018-04-22  Tom Tromey  <tom@tromey.com>

	* cli-out.c (cli_ui_out::out_field_fmt): Remove.
	(cli_ui_out::do_field_string): Use fputs_filtered.
	* cli-out.h (class cli_ui_out) <out_field_fmt>: Remove.
