[PATCH initramfs-tools 07/11] update-initramfs: Consistently show which options take arguments



The text in the manual page implies that -b needs an argument
but the usage summaries don't say that.

While we're at it, remove the brackets in '-k [version]', as
these suggest the version argument is optional.

Closes: #762768
