build: fix ninja build failure (GYP patch)

Currently the files specified in libraries in node.gyp `cctest` target are
getting a '.lib' extension on windows when generated with ninja.
This commit adds a check to see if a file has a '.obj' extension and in
that case no '.lib' extension will be added.

Also, the LIBS specified in the 'libraries' section are not
being included in the --start-group --end-group section which
means that these libraries will not be searched causing issue
with linkers where the order matters.
