crypto/x509: matching any requested EKU should be sufficient.
The documentation was unclear here and I misremembered the behaviour and
changed it in 1.10: it used to be that matching any EKU was enough but
1.10 requires that all EKUs match.
Restore 1.9 behaviour and clarify the documentation to make it official.
Fixes #24162.
