t/chainlint.sed: drop extra spaces from regex character class

This character class, like many others in this script, matches
horizontal whitespace consisting of spaces and tabs, however, a few
extra, entirely harmless, spaces somehow slipped into the expression.
Removing them is purely a cosmetic fix.

While at it, re-indent three lines with a single TAB each which were
incorrectly indented with six spaces. Also, a purely cosmetic fix.
