This applies the second part of GDB's End of Year Procedure, which
updates the copyright year range in all of GDB's files.
gdb/ChangeLog:
Update copyright year range in all GDB files.
The major reason this header was needed, bfd_default_set_arch_mach,
has now moved to bfd.h.

2. The use of a single year range, instead of potentially multiple
year ranges, as approved by the FSF.
