gdbsupport: make filtered_iterator::operator* return the same thing as underlying iterator
This is the same idea as the previous patch, but for filtered_iterator.
Without this patch, I would see this when applying the patch that
removes reference_to_pointer_iterator from breakpoint_range:
CXX breakpoint.o
/home/smarchi/src/binutils-gdb/gdb/breakpoint.c: In function ‘void download_tracepoint_locations()’:
/home/smarchi/src/binutils-gdb/gdb/breakpoint.c:11007:41: error: cannot allocate an object of abstract type ‘breakpoint’
11007 | for (breakpoint &b : all_tracepoints ())
