Don’t set print-escape-newlines in the minibuffer

This appears to be an unnecessary and possibly-confusing
revenant from ancient code (Bug#31251).  See thread containing:
https://lists.gnu.org/r/emacs-devel/2018-04/msg00654.html
* src/minibuf.c (read_minibuf): Do not set print-escape-newlines.
* src/print.c (syms_of_print): Do not defsym print-escape-newlines
or print-escape-control-characters, as these symbols are not used
in C code.
