kmod: add patches to support build on Redhat 5

kmod uses certain features not available on older Redhat 5 machines.
This commit imports two patches from OpenEmbedded to fix that.

+Subject: [PATCH] libkmod/libkmod-internal.h: check whether O_CLOEXEC is
+ defined or not
+
+O_CLOEXEC is introduced from Linux 2.6.23, so old kernel doesn't have
+it, we need check before use.
+
+This patch is much more like a workaround, since it may need fcntl() use
+FD_CLOEXEC to replace.
+
+This problem was reported by "Ting Liu <b28495@freescale.com>"

+Subject: [PATCH] Change to calling bswap_* instead of htobe* and be*toh
+
+We can't use htobe* and be*toh functions because they are not
+available on older versions of glibc, For example, shipped on Centos 5.5.
+
+Change to directly calling bswap_* as defined in+byteswap.h.
