fix shared lib install

We need the shared library to go into /usr/lib64 on 64bit systems,
so make sure the install path can be controlled via a variable so
the ebuild can set it.

While we're here, fix the install perms.  Shared objects should be
+x since we need to map executable pages out of it.

BUG=chromium-os:20636
TEST=`emerge-x86-alex gestures` installs into /usr/lib64 now
