doc-postprocess.pl: Un-break tag file references

* util/doc-postprocess.pl: For some reason, recent versions of
Doxygen output the full path to referenced tag files.  This is
bad since it breaks doc-install.pl, and also because it leaks
local path names into source tarballs.  Thus, strip the directory
prefix here.
