README: cleanup requirements for pkg-config

FreeBSD fully supports pkg-config; the .pc files for the internal
libusb has been added with
https://cgit.freebsd.org/src/commit/?id=041d3f3f09b8
and became part of FreeBSD 10.0 in 2014-01-16.

Remove the obsoleted requirements for adding .pc files.

While there, add pkgconf as an alternative to pkg-config.
