[PATCH GSoC] gitweb: Add global installation target for gitweb

The current installation of gitweb requires us to give it a
target directory. But splitting of gitweb makes it difficult
for git instaweb to continue with the current method.

This commit allow installation of gitweb files into the target
'$(sharedir)/gitweb' by default when user type 'make install'.
This target act as root directory for instaweb servers.

This is necessary step to acheive the goals of my GSoC project.
Currently instaweb script creates gitweb.* files in every repository
which is unnecessary. So if we have global folder for gitweb files we
can configure the instaweb server root to point to that direction.
