tls: don't select STREAM_PARSER

tls: don't select STREAM_PARSER

ktls was converted to its own stream parser in commit
84c61fe1a75b ("tls: rx: do not use the standard strparser"), but the
Kconfig dependency was left. The only part of the original strparser
that's shared with ktls are a few structs (strp_msg, sk_skb_cb) and
the strp_msg helper, those don't require building the net/strparser
code.
