cbfstool: accept read-only files when possible
cbfstool tries opening the input file for write access even if the
command does not require modifying the file.
Let's not request write access unless it is necessary, this way one
can examine write protected files without sudo.
BRANCH=none
BUG=none
TEST=running
cbfstool /build/<board>/firmware/image.bin print
in chroot does not require root access any more.
