curlpp: Fix packaging and reference to license

This patch fixes three issues:

1. The recipe used "libcurlpp" for its package base name. It defined
  PACKAGES and corresponding package contents manually, but the
  non-standard naming led to an error message when trying to depend on
  it (nothing provides curlpp needed by curlpp-dev).

  See also
  https://lists.yoctoproject.org/pipermail/poky/2018-February/011236.html.

  Fixed by removing PACKAGES and corresponding FILES_*, relying on
  automatic packaging now.

2. Upstream ships a license file (MIT), which is referenced by the
  recipe now (instead of the stock COPYING.MIT file).

3. There was a do_install_append() function which patched the
  installed curlpp.pc file. Since it seemed to be of no use, it was
  removed.
