Use loaded_from only when non-nil

For a gem which is not installed in specified path
"loaded_from" will return nil and hence check for builtin_gem?
will throw error.

Fixes #2915, #2963
Fix deploying git gems without git (#2968)

If git isn't allowed to run, we don't blow up if we don't have it.
good grief why a proc it doesn't change
no more weird-looking if/else
uh, false is not nil :P
turns out it's not static after all :\

weirdest use of a closure ever

switch to an explicit circular reference, instead of an implicit
one via the closure. still not happy about it, though.
Print warning when bundler is run by root.

When a user runs bundle install with sudo bundler will print a warning, letting
them know of potential consequences.

closes #2936
move install warning into Install, add word-wrap
root warn spec to sudo specs
and it's not always set, obviously
