Hello,

the problem is a missing export from crypt32.dll.
Steam imports various functions from crypt32 and advapi32.
When one of the crypt32 imports can't be found, an internal import error flag
is set.
Later this leads to a certain code path being skipped which imports additional
crypt functions from advapi32.
> From another code path the steam client tries to call one of the skipped

imports (null ptr), leading to crash caught by their internal crash handler.

Add a stub for crypt32.PFXVerifyPassword() and steam will no longer crash,
displaying system information summary.

$ wine --version
wine-1.3.21-92-gb6484cc
