Move finish_print out of value_print_options

'finish_print' does not really belong in value_print_options -- this
is consulted only when deciding whether or not to print a value, and
never during the course of printing.  This patch removes it from the
structure and makes it a static global in infcmd.c instead.

Tested on x86-64 Fedora 34.
