Use more descriptive algorithm names in skip messages.

Test Plan

• faked that ccr0 couldn't do AES in cryptotest.py and then ran it with -v.

No objection, although it's somewhat moot because the lists are shared (aesmodules, shamodules). Unless you plan to change that.

[jhb]

It is mostly moot and I don't really plan to change it currently. At some point I might instead make it just try to create a single test session for each algorithm up front and skip if it gets EOPNOTSUPP. It also should not have a hardcoded list of device names. It should really take an optional command line argument for what devices you want to test or use some method to enumerate the available devices (might have to add something to OCF to support the latter).

LGTM! Please commit this change to ^/head.
