start-ssh-agent: Fix bashism.

A sequence of assignments like

  foo=mumble bar=$foo/twonk

in bash is expanded from left-to-right, so bar is assigned the value
mumble/twonk.  Unfortunately, some shells don't process assignments
left-to-right in this way, and bar ends up as just /twonk.

Insert semicolons to force sequencing.
