Fix legacy blockdevice vendor and size facts not resolving

After commit https://github.com/puppetlabs/facter/commit/4d5f4a59dd168a02be7e47ed94c9c3452955eee4 which changed regex facts to be resolved using their name instead of the user query, some legacy blockdevice facts failed to resolve.

This was due to an extraneous ' in the alias list, which was treated as part of the fact name. This affects blockdevice_size facts on AIX, and blockdevice_vendor facts on Linux and Solaris.

Proposed PR: https://github.com/puppetlabs/facter/pull/2238
