[PATCH] Drop alternative when conditional dependency

[Hector Oron <hector.oron@gmail.com>]

  Trying to add an alternative build dependency on debian-installer:

    module-init-tools [linux-any] | kmod [linux-any]

  It breaks buildscript logic, as regex parsing dpkg-checkbuilddeps
  output does not support alternatives.

  This patch drops alternatives from the output of packages listed
  by dpkg-checkbuilddeps.
