bp_signup_requires_privacy_policy_acceptance() fails to check WP version and fails on earlier versions

[Venutius]

The WP Function get_privacy_policy_url() was introduced in WP Version 4.9.6 however the BP function bp_signup_requires_privacy_policy_acceptance() does not check for that version before trying to execute get_privacy_policy_url(). Therefore users running earlier versions of WP will see undefined function errors when using later versions of BP.

A possible fix for this is to add the following line to plugins/buddypress/bp-members/bp-members-template.php line 2421, just after the function bp_signup_requires_privacy_policy_acceptance() is declared:

if ( version_compare( $GLOBALS['wp_version'], '4.9.6', '<' ) ) return false;

Thanks for noting this, @Venutius.

In 12336:

Members: Bail from bp_signup_requires_privacy_policy_acceptance() on older WP.

This helps avoid fatal errors in certain cases.

Props Venutius.
Fixes #8049.
