…#112)

Currently AbstractGpgMojo has a fixed set of supported signers (and how
they are constructed), it would be good to allow extensions (e.g. Tycho
is also using AbstractGpgMojo) to possibly override that aspect.

This extracts the creation of the signer into a (protected) method so
different types or alternative implementations can be used.

This is really just "build time" as at runtime it uses
given Maven version artifacts anyway.

Since 3.2.0 version we always appended "line separator" to passphrase unless it itself ended with one. But, this caused problem on Windows, as (our assumption is) that GPG uses binary read of STDIN, and on Windows "line separator" is "\r\n", while GPG handles "\n" only, making passphrase corrupted by presence of unwanted "\r".
