[PATCH] Makefile: build 'gitweb' in the default target

["SZEDER Gábor" <szeder.dev@gmail.com>]

Our Makefile's default target used to build 'gitweb', though
indirectly: the 'all' target depended on 'git-instaweb', which in turn
depended on 'gitweb'.  Then e25c7cc146 (Makefile: drop dependency
between git-instaweb and gitweb, 2015-05-29) removed the latter
dependency, and for good reasons (quoting its commit message):

  "1. git-instaweb has no build-time dependency on gitweb; it
      is a run-time dependency

   2. gitweb is a directory that we want to recursively make
      in. As a result, its recipe is marked .PHONY, which
      causes "make" to rebuild git-instaweb every time it is
      run."

Since then a simple 'make' doesn't build 'gitweb'.

Luckily, installing 'gitweb' is not broken: although 'make install'
doesn't depend on the 'gitweb' target, it runs 'make -C gitweb
install' unconditionally, which does generate all the necessary files
for 'gitweb' and installs them.  However, if someone runs 'make &&
sudo make install', then those files in the 'gitweb' directory will be
generated and owned by root, which is not nice.

List 'gitweb' as a direct dependency of the default target, so a plain
'make' will build it.
