add mingw_gcc_compiler config_setting to add_build_file.patch

[vvviktor]

Building zlib under Windows MINGW GCC toolchain fails with [-fpermissive] errors.

Here is failure reproduction example. The command is bazel build @zlib//:zlib

Toolchain along with setup instructions is here.

My workaround is to add config_setting rule for mingw-gcc compiler. So it will add -fpermissive flag if CCToolchainInfo.compiler is set to mingw-gcc.
