cygport: TeX Live postinstall scripts shouldn't enable all formats

[Ken Brown]

I've just discovered that some TeX Live packages have formats that are 
supposed to be disabled by default.  This is indicated by the presence 
of "mode=disabled" in the "execute AddFormat ..." line in the .tlpobj 
file.  The documentation for this is in 
/usr/share/tlpkg/TeXLive/TLPSRC.pm.  But the postinstall scripts 
generated by cygport enable these formats anyway.  The attached patch 
fixes this.
