[SV 57967] Only set APPEND mode for regular files

APPEND is a permanent mode shared by all users of a file.  If we
set it on a tty, pipe, etc. it will stay in effect even after make
exits, which can cause problems.

Patch provided by 0xef967c36@gmail.com

* src/output.c (set_append_mode): Check for a regular file.
