Subject: [PATCH 2/3] scripts/decode_stacktrace.sh: clarify command line

The syntax as expressed by usage() is not entirely correct: "<modules
path>" cannot be passed without "<base path>|auto". Additionally human
reading of this syntax can be subject to misunderstanding due the mixture
of '|' and '[]'.

Improve readability in various ways:
 * rewrite using two lines for the two allowed usages
 * add square brackets around "<vmlinux>" as it is optional when using
   debuginfod-find
 * move "<modules path>" to inside the square brackets of the 2nd
   positional parameter
 * use underscores instead of spaces in <...> strings
