runtests: do CRLF replacements per section only

The `crlf="yes"` attribute and "hyper mode" are now only applied on a
subset of dedicated sections: data, datacheck, stdout and protocol.

Updated test 2500 accordingly.

Also made test1 use crlf="yes" for <protocol>, mostly because it is
often used as a template test case. Going forward, using this attribute
we should be able to write test cases using linefeeds only and avoid
mixed line ending encodings.

Fixes #10009
Closes #10010
