Make building of pepper_test_plugin only happen on Linux....

Make building of pepper_test_plugin only happen on Windows.
In the previous CL I made the build of pepper_test_plugin conditional
but forgot to remove the unconditional reference, leaving the build breakage
on Linux.

Dear Sheriffs,

My previous commit introduced a fail on Linux release that was due to building
Skia and others on 64-bits in some way they don't like.  I had intended to have
the building of those portions of the test plugin be conditional, but goofed. 
If you would like, I can revert the previous CL, or if you approve this CL it
should fix the regression.  Your choice.

LGTM but please watch the tree after this lands.

I've been watching and there seems to be no residual problem except one
possibility that I don't quite understand: "Webkit Linux failed
webkit_tests".  The log appears to show problems running apache.  Any
insights?

These are "timeout 1200 sec no output" failures, yes?  Unlikely to be you.
 We saw this earlier in the day; when we ran apache by hand it yelled about
"out of space on device" when trying to grab or create a lock.  (Disk was
not full).  Reboot of bot fixed it.  Don't know how intermittent the hang
problem is or what triggers it or how new it is.
