kmod-native_git.bb: fix builds for hosts with older libc

Browse Source 
kmod will fail to build with the following error because O_CLOEXEC is
not defined:

| libkmod/libkmod-module.c: In function 'kmod_module_get_initstate':
| libkmod/libkmod-module.c:1640: error: 'O_CLOEXEC' undeclared (first use in this function)
| libkmod/libkmod-module.c:1640: error: (Each undeclared identifier is reported only once
| libkmod/libkmod-module.c:1640: error: for each function it appears in.)
| libkmod/libkmod-module.c: In function 'kmod_module_get_refcnt':
| libkmod/libkmod-module.c:1754: error: 'O_CLOEXEC' undeclared (first use in this function)
| libkmod/libkmod-module.c: In function 'kmod_module_get_sections':
| libkmod/libkmod-module.c:1913: error: 'O_CLOEXEC' undeclared (first use in this function)
| libkmod/libkmod-file.c: In function 'kmod_file_open':
| libkmod/libkmod-file.c:282: error: 'O_CLOEXEC' undeclared (first use in this function)
| libkmod/libkmod-file.c:282: error: (Each undeclared identifier is reported only once
| libkmod/libkmod-file.c:282: error: for each function it appears in.)

Since we are only using kmod-native for depmod, and it's a non-threaded
user of this libary being built this should be safe to override O_CLOEXEC.

Keep in mind this is ONLY effecting the native builds and not what is
being shipped in the root file system.
