Use boolean tag (0x01) for boolean type.

Fix for problem with ReadASN1Boolean, which uses invalid tag (Integer / 0x02) when trying to read boolean value. This is a fix for the one case mentioned in "x/crypto/cryptobyte: cannot read boolean values #26565"
This is specified in ITU-T X.690, section 8.2, with DER additions specified in 11.1.
