Subject: [PATCH] Fix Shellcheck SC2197

This PR fixes one Shellcheck issue:

      In testssl_3.1dev_20200208.sh line 2395:
                HEADERVALUE="$(fgrep -Fai "$key:" $HEADERFILE | head -1)"
                               ^-- SC2197: fgrep is non-standard and deprecated. Use grep -F instead.

The man page for grep states that fgrep is the same a grep -F and that grep is deprecated. So, fgrep -F is just redundant.
