lib: asn1_decoder - add MODULE_LICENSE("GPL")

A kernel taint results when loading the rsa_generic module:

root@(none):~# modprobe rsa_generic
asn1_decoder: module license 'unspecified' taints kernel.
Disabling lock debugging due to kernel taint

"Tainting" of the kernel is (usually) a way of indicating that
a proprietary module has been inserted, which is not the case here.
