databases/mysql80-client: Fix mysqlclient.pc

- Bump PORTREVISION for package change

Not all supported FreeBSD releases has openssl.pc in base system. This patch
adds a check for openssl.pc. It helps to build databases/py-mysqlclient.

If you do not have openssl.pc from your SSL provider.

Before the fix:
% grep Requires.private: /usr/local/libdata/pkgconfig/mysqlclient.pc
Requires.private: openssl

After the fix:
% grep Requires.private: /usr/local/libdata/pkgconfig/mysqlclient.pc
Requires.private:

The build log [1] of databases/py-mysqlclient without the fix:
===>  Building for py39-mysqlclient-2.2.0
* Getting build dependencies for wheel...
Package openssl was not found in the pkg-config search path.
Perhaps you should add the directory containing `openssl.pc'
to the PKG_CONFIG_PATH environment variable
Package 'openssl', required by 'mysqlclient', not found
