build_linux.sh - remove fdocore component

[mloskot]

IMO, it would be reasonable to remove fdocore from the list (./build_linux.sh --help) of available components.

Here is my short discussion with Greg:

[00:46]  <gregboone_> fdocore is Fdo and Utilities
[00:46]  <mloskot> Honestly, I think it might be confusing
[00:46]  <gregboone_> Yes it is
[00:46]  <mloskot> it's better to list all components separately
[00:47]  <mloskot> and user will be able to combine them as he likes
[00:47]  <gregboone_> Utilities is listed, as well and fdo and Providers
[00:47]  <gregboone_> they can be combined as needed
[00:48]  <gregboone_> fdocore is a holdover from the time we had numerous svn respositories
[00:48]  <gregboone_> and fdocore was the 'key' one
[00:48]  <gregboone_> we may be able to remove it
