x/crypto/pkcs12: typo in struct tag

[tipycalFlow]

Hi,

I was trying to use the pkcs12 package's Decode method to read a .p12 file to further generate a TLS certificate and got the following error:
pkcs12: expected exactly two safe bags in the PFX PDU

I looked around the code in pkcs12.go and came across what seems to be a typing error. So my question is, should line 68:
Value asn1.RawValue 'ans1:"set"'
be:
Value asn1.RawValue 'asn1:"set"'
instead?

**I'm using go1.6beta1 darwin/amd64 on OS X Yosemite version 10.10.5 (14F1509)

@tipycalFlow this looks like a straight forward bug fix, do you want to take a go at fixing it, possibly including a test to make sure it doesn't regress ?

Actually, I'm not sure if this actually is a typo or it is intended as is. I just thought I'd bring it to the notice of the dev team
