utags: import ANDROID_GKI_VFS_EXPORT_ONLY namespace for kernel_read

Browse source 
kernel_read and kernel_write are exported with specific ANDROID_GKI_VFS_EXPORT_ONLY
namespace, so the DLKM should import the namespace.

error log:
[   12.547678] utags: module uses symbol (kernel_read) from namespace VFS_internal_I_am_really_a_filesystem_and_am_NOT_a_driver, but does not import it.
[   12.561432] utags: Unknown symbol kernel_read (err -22)
