mac: Fix HighDPI mode on 10.7.3

Apparently omission of the NSPrincipalClass key sends an app down
the magnify mode path starting with 10.7.3. Thanks to
YAMAMOTO Mitsuharu for figuring this out:

Hmm. I thought we already had this.

LGTM otherwise.

Please keep this sorted. NSPrincipalClass <
NSSupportsAutomaticGraphicsSwitching.

`git log -S NSPrincipalClass chrome/app/app-Info.plist` tells me that we used to
have this, but it was removed in http://codereview.chromium.org/345051

dmac, do you remember why you removed NSPrincipalClass from our Info.plist?
