Update to version 11.1.0

In terms of functionality this update is a no-op on
FreeBSD. Some local patches were upstreamed and have
been removed from the port.

Tested matrix is ESXi 6.5 and 6.7, and Fusion.
FreeBSD HEAD, 12.1-R, 12.0-R and 11.3-R AMD64

The test plan ensures the VM power control works from
the management app, that the memory balloon driver operates
properly, and that reporting back to vCenter as far as IP
and whether the tools are installed and operational works.

In particular no i386 versions of FreeBSD were
explicitly tested, nor was any testing done on ESXi 7.0

The new functionality in this version of the tools is Windows/Linux
only. See the listed PR for the pieces FreeBSD needs to achieve parity.
