Outdated SHA in openblas64-julia.rb

[ngcrawford]

I got this error when trying to install 64 bit julia:

#################################################### 100.0%

Error: SHA1 mismatch
Expected: d012ebc2b8dcd3e95f667dff08318a81479a47c3

(To retry an incomplete download, remove the file above.)

Updating the formula to the 'actual' SHA fixed the install error:

I think the 32 bit openblas-julia.rb may also need to be updated.

I was pretty confused by this as I manually downloaded the .tar.gz and the SHA matched the "old" SHA..... until I realized that I have openblas64-julia downloading the zipball, and openblas-julia downloading the tarball!

I've changed both to download the tarball now, but your installation should be fine, so no need to remove and reinstall.
