src: indent long help text properly

The previous code passed an ignored argument to StringPrototypeTrimLeft,
and tried to trim a string that didn't start with whitespace. The trim
makes more sense after the indentation has been added. Now wrapped lines
actually show up with the rest of the help text.

Doing this made an uncharacteristic trailing newline in the
`--icu-data-dir` help text more obvious, so I removed that.
