[PATCH] xen: Fix XEN_EXTRAVERSION after 4.19-rc1

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

EXTRAVERSION needs a . separator for numbers.  Currently, the banner reports:

  __  __            _  _    _  ___   ___
  \ \/ /___ _ __   | || |  / |/ _ \ / _ \    _ __ ___
   \  // _ \ '_ \  | || |_ | | (_) | | | |__| '__/ __|
   /  \  __/ | | | |__   _|| |\__, | |_| |__| | | (__
  /_/\_\___|_| |_|    |_|(_)_|  /_/ \___/   |_|  \___|

and xl reports:

  # xl info xen_version
  4.190-rc

Fixes: 4a73eb4c205d ("Update Xen version to 4.19-rc")

For 4.19.  This is a minor mistake when creating Xen-4.19-rc1.
