getdeps.sh fails on windows when applying patch to boost

[fmoo]

When running getdeps.sh on Windows (via git/mingw bash), I get the following error when it tries to patch boost:

Building on {distro=None, distro_vers=10, fb=off, fbsource=off, os=windows, shared_libs=off, test=on}

During handling of the above exception, another exception occurred:

Updating the second to last line of the patch to include a single whitespace seems to fix it locally for me:

After this, I got all the way up to folly, which failed with:

CMake Error at C:/source/proxygen/_build/boost-Ct8ZMk_J_pyqyHLfrydelwvlfzw-NfC_5D8VmaRrOvw/lib/cmake/Boost-1.83.0/BoostConfig.cmake:141 (find_package):

  but it set boost_context_FOUND to FALSE so package "boost_context" is
  considered to be NOT FOUND.  Reason given by package:

  No suitable build variant has been found.

  The following variants have been tried and rejected:

  * boost_context-vc143-mt-x64-1_83.lib (vc143, detected vc141, set

lmk if I should open a separate issue for that or what.
