    Cygwin: Makefile: Drop all the "test dll" considerations
    
    After 90236c3a2cf6, the testsuite is failing, as the cygwin0.dll
    referenced by the implib that testsuite programs are linked with doesn't
    exist anymore.
    
    We don't need to make and link the testsuite with a specially named DLL,
    as the cygwin DLL (since 526b0fbca377) takes into consideration the path
    it's executing from to define separate "Cygwin installations", which
    don't interact.
    
    Fixes: 90236c3a2cf6 ("Cygwin: Makefile: build new-cygwin1.dll in a single step")
