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
