connectors/local: fix conditional line breaks

Problem: the local connector uses a line break style in
conditionals that is inconsistent with the coding style
of most of the flux-core code base.

Ensure there is a line break after an "if" block's closing
brace, before "else".

When multi-part conditional expressions are broken across
lines, indent the second condition 4 spaces from the first.
