    books/porters-handbook: Add USES=tex macro
    
    In a recent commit I have changed USE_TEX macros to USES=tex in the
    ports tree. Till now there were in fact no descriptions of TEX macros at
    all. So introduce the new macros here in the porters-handbook.
    
    While I am here remove EOL spaces.
