Make.Rules: fix INDENT test

The indent variable has a test to see if indent is installed, but the test
logic is inverted and has a typo in the binary name.

[Ed. The typos were part of my tests that the tests were working, and
then I absent mindedly checked it in!?! Thanks Mike for spotting
it. :*) ]
