os: TestProgWideChdir fails on OS X 10.10

--- FAIL: TestProgWideChdir (0.00s)
    os_test.go:1089: Getwd returned "/private/var/folders/2g/gfk3yj9d4318d1x3j8jgkjjw0000gn/T/test083221789" want "/var/folders/2g/gfk3yj9d4318d1x3j8jgkjjw0000gn/T/test083221789"

TMPDIR is set to a path under /var/folders by default, and it looks like OS X 10.10 moved /var with a symlink:

lrwxr-xr-x@ 1 root wheel 11 Oct 9 2014 var -> private/var

The builders do not show this error, presumably because they are running an older version of OS X. The new buildlet (still under construction) should let us run older versions of OS X under a VM, so hopefully we can test for this in the future.

Ahh, and we only have 10.6 builders running on the dashboard at the moment.
