cflags for vendor variants

cflags that are only applied when building the vendor variant of a lib
is now supported. This will be particularily useful when existing macro
should be turned off for the vendor variant:

cflags: ["-DENABLE_FEATURE_X"],

target: {
    vendor: {
        cflags: ["-UENABLE_FEATURE_X"],
    },
},

Without this, the library author has to undef the macro inside the
source code using __ANDROID_VNDK__, which is not desired especially for
external projects.
