[NaCl Addin] Fix dependencies in visual studio

This fixes a long standing issue where visual studio
would always attempt to re-build, and in particular
relink NaCl project.

The primary fix here is to make filenames in the .tlog
files always uppercase and always absolute.

The secondary fix is to make the linker step also honour
tlog dependencies so that MSBuild knows when it can skip
the link step.
