[PATCH v3 1/3] docs: admin-guide: Handle TAINT_FORCED_BIND when parsing /proc/sys/kernel/tainted

[Uwe Kleine-König]

tainted-kernels.rst contains a small script to check which taint bits
are set in /proc/sys/kernel/tainted. Add one more loop iteration to also
handle the newly added TAINT_FORCED_BIND bit.

Also simplify by starting the loop at 0 and save substracting 1 for each
usage of the loop counter.

 which bits are set::
