Fixed install-xxx functionality broken in 9628e27d

Fixed install-xxx functionality broken in 9628e27d

Only the CPack component definitions needed fixing, inasmuch as they
are what is used for the "make install-xxx" functionality. I separated
"libraries" component into "libraries", "libraries-gmxpreprocess" and
"libraries-gmxana" for, respectively, the core gmx/md/etc. libraries,
and those particular to src/kernel programs and src/tools programs.
Now "make install-xxx" correctly compiles, links and installs only the
required dependencies, and the wrong dependencies introduced in the
above commit are removed.

Fixes #1015
