drbd-utils: Fix a udev rule reproducibility

drbd-utils configure step check the build host udev version to enable
or disable the target udev rule. This leads to a clear
non-reproducibility.

This patch fixes this by adding a configure option to the configure step
which allows to skip the udev version checks and unconditionally enable
the udev rule.

+Subject: [PATCH] configure.ac: Add an option to disable host udev version
+ checks
+
+In cross-compilation environment, the build host might have an outdated
+udev or no udev at all. But the user may still want to build with the
+enabled udev rule (for its udev-enabled target).
+
+This patch adds a "--disable-udevchecks" option the disable build host
+udev version check at configure-time and unconditionally install the
+enabled udev rule. Without this new option, the behavior stays the same
+(checks enabled).
