fetch_packages: Add 'autoreconf' ivocation for the Thrift package

Patches for the Thrift modify its Makefile.am and the configure script
has to be regenerated. If autoreconf is not relaunch it causes errors
if the versions of aclocal, autoconf or automake differs on the build host
differ from those used while creating the package.

packages: Add International Components for Unicode fetching

This has been added as on FreeBSD platform it has to be build from source.
A version available in pkg repository uses libcxxrt ABI library, whereas
rest of the agent is build with libsubc++ that are not compatible with
each other and are causing the Agent to crash.
