Edward Welbourne b9557296cb Fix crash when reading a PKCS12 file with no private key
The only reason our code wants PKCS12 files is for a private key, but
a valid file needn't contain one; and reading a file without lead to a
crash in QSslKeyPrivate::fromEVP_PKEY().  So check for missing key and
fail the load, since the file is useless to us.  Also ensure the
caller's pkey is initialized, as we aren't promised that
PKCS12_parse() will set it when there is no private key.

Add a test for this case (it crashes without the fix) and update the
instructions for how to generate test data to cover it also.
(Corrected the wording there, too; at the interactive prompt,
"providing no password" really provides an empty password.)

The PKCS#12 bundle was created by running the following in an
interactive shell in ../../qsslsocket/certs/:
openssl pkcs12 -export -in leaf.crt \
-inkey leaf.key -out leaf.p12 \
-certfile inter.crt -CAfile ca.crt
An empty password was provided (twice). The pkcs.crt and pkcs.key
files were then copied here and leaf.p12 was moved here.
The test-case with no private key (in a valid PKCS12 file) was created
similarly but with the command adjusted to:
openssl pkcs12 -export -in leaf.crt \
-nokeys -out leaf-nokey.p12 \
-certfile inter.crt -CAfile ca.crt
The file leaf-nokey.p12 was then moved here.
