Subject: scripts/decode_stacktrace.sh: indicate 'auto' can be used for base path

Add "auto" to the usage message so that it's a little clearer that you can
pass "auto" as the second argument.  When passing "auto" the script tries
to find the base path automatically instead of requiring it be passed on
the commandline.  Also use [<variable>] to indicate the variable argument
and that it is optional so that we can differentiate from the literal
"auto" that should be passed.
