Add lib.target to chrome-wrapper's LD_LIBRARY_PATH.

Add lib.target to chrome-wrapper's LD_LIBRARY_PATH.

Needed since r732 of gyp.

TEST=Shared build on linux finds libs now without needing to
manually adjust LD_LIBRARY_PATH.

Please review. Thank you.

I wonder if we shouldn't just change gyp to create 'lib.target' as 'lib'
(basically the way it was before). If the intent of that change was to
distinguish the host from the target binaries, simply creating 'lib' and
'lib.host' does that. All adding 'lib.target' does is make it into a
backward-incompatible change that breaks stuff like this, as well as making it
inconsistent with other builders which just have 'lib'. [adding evan because I
know he had similar objections to 'obj.target']

By the way, the gyp change that this is needed for is
http://code.google.com/p/gyp/source/detail?r=732, not r737. [adding piman who
made that change]

Ugh, really adding piman this time.

It's arguable, we could special-case toolset==target, but I think it adds
complexity where none is really needed.

Ah, I misread the commit log, sorry. I will fix the description and probably
land this in a couple of hours if there are no objections to keeping the
lib.target scheme.

OK, LGTM.
