[OSX, docs] update some release build informations

- switching release builds to 10.7
- release binary looks like 64bit only
- tested up to 10.10
- gitian builder builds against 10.7. The docs should be consistant.
- remove 32bit text because nowadays it's obvious to support 64bit only on OSX.

In order to build a working toolchain, the following source packages are needed
from Apple: cctools, dyld, and ld64.

Beware. This part is ugly. Very very very ugly. In the future, this should be
broken out into a new repository and cleaned up. Additionally, the binaries
only work when built as x86 and not x86_64. This is an especially nasty
limitation because it must be linked with the toolchain's libLTO.so, meaning
that the entire toolchain must be x86. Gitian x86_64 should not be used until
this has been fixed, because it would mean that several native dependencies
(openssl, libuuid, etc) would need to be built as x86 first.

These tools inject timestamps by default, which produce non-deterministic
binaries. The ZERO_AR_DATE environment variable is used to disable that.

-----

* Tested on OS X 10.6 through 10.9 on 64-bit Intel processors only.
Older OSX releases or 32-bit processors are no longer supported.
* Tested on OS X 10.7 through 10.10 on 64-bit Intel processors only.

* All of the commands should be executed in a Terminal application. The
built-in one is located in `/Applications/Utilities`.

bundle is packaged and signed to create the .dmg disk image that is distributed.
