add missing settings to CrittercismSDK 4.3.3

After updating CrittercismSDK to 4.3.3, a missing error of dsym_upload.sh occurs

> Pods/CrittercismSDK/CrittercismSDK/dsym_upload.sh: No such file or directory

And comparing with 4.3.2 podspec file, adding these settings would make a go.

Plz test if this workds.
