support/scripts: fix graph-depends when run with python3

Make graph-depends script opening the output file in text mode since only ascii characters will be written.

This change fixes the following error occuring when the default host python interpreter is python3:

make: Entering directory '/opt/buildroot'
Getting targets
Getting dependencies for ['toolchain-external', 'toolchain', 'busybox', ...] Getting dependencies for ['host-python3', 'host-pkgconf', 'host-gettext', ...] Getting dependencies for ['host-libxml2', 'host-swig', 'host-m4', ...] Getting version for ['toolchain-external', 'toolchain', 'busybox', ...] Traceback (most recent call last):
File "/opt/buildroot/support/scripts/graph-depends", line 425, in <module>
outfile.write("digraph G {\n")
TypeError: a bytes-like object is required, not 'str' Makefile:807: recipe for target 'graph-depends' failed
make[1]: *** [graph-depends] Error 1
Makefile:84: recipe for target '_all' failed
make: *** [_all] Error 2
make: Leaving directory '/opt/buildroot'

While with python2, adding 'b' to the openning mode has no effect on Linux (c.f. [2]), the above error is expected with python3 (c.f. [1]).

Therefore, just open the outfile in default (i.e. text) mode.
