[ptxdist] [PATCH 1/5] package templates: add code-signing-provider template

[Bastian Krause <bst@pengutronix.de>]

A ptxdist code signing provider is a package which selects the required
host tools needed for the code signing helpers to work. A shell script
is needed to define roles, set PKCS#11 URIs and import keys if SoftHSM
is used. In order to simplify its creation provide a template along with
an example script.
