[PATCH 4/8] foll-vfork.c/vforked-prog.c: Add copyright headers.

[Pedro Alves <palves@redhat.com>]

I wanted to copy and adjust foll-vfork.c for a new test, and noticed
that those files miss copyright headers.  This patch adds them.  To
know which years to use, I went back in history and saw that these
files were added at the same time as foll-vfork.exp (gdb 4.8).  I then
just copied the years from that file.
