no-sse2.patch: Fix/simplify disable_sse2 logic in breakpad/src/build/common.gypi
    
    That file is not really used in QtWebEngine anyway, but simply
    defaulting disable_sse2 to 1 is the right thing. The variable is ignored
    on everything other than ia32 (i686) anyway, even on x64 (x86_64). And
    setting conditional defaults might not work as expected in gyp.
