[PATCH] ipipe: genpatches.sh: allow overriding the default version label

[Philippe Gerum <rpm@xenomai.org>]

From: Philippe Gerum <rpm@xenomai.org>

In order to support localversion* variants like -cip, the automated
patch generator needs to override the default version label used by
genpatches.sh with 4.4 and 4.9 legacy kernels.
    
Use --label to override the default kernel version label in the output
file name. Otherwise, use the kernel release stamp.
