gnu: Rename escpr to epson-inkjet-printer-escpr.

‘escpr’ is nice and short, but everyone else calls this package
‘epson-inkjet-printer-escpr’.  More importantly, so does upstream.

* gnu/packages/cups.scm (escpr, epson-inkjet-printer-escpr,): Rename
escpr to epson-inkjet-printer-escpr, redefining escpr as
deprecated-package.  Adjust all users.
