please.sh upgrade: learn about GNU TLS

The 32-bit version of GNU TLS is currently broken because we inherit
MSYS2's version, and it was not rebuilt when its dependencies
`libhogweed` and `libnettle` were upgraded to versions whose `.dll` file
names changed (and therefore GNU TLS is currently broken).
