Upgrade folly to v2018.10.22.00 for Android (facebook#21977)

Summary:
Fixes facebook#20302 (For Android)

Note:
------
1. New folly will have build break for a gcc-4.9 and gcc-4.9 seems to be deprecated for latest folly.
    As we only use partial folly implementations, I just fixed the build break part.
    To support building RN on Windows, the patches are written by gradle ReplaceTokens.

2. The change for glog copying header into exported/ is to prevent build break for folly.
    `folly/detail/Demangle.h` will try to use libstdc++'s demangle.h. Unfortunately, glog also has a demangle.h in source code. So I copy exported headers and only search headers in exported/ folder during build.
