[build] Set -Wno-strict-prototypes.

https://reviews.llvm.org/D122895 changed the semantics of
-Wstrict-prototypes, which causes -Werror build failures in the core
builders. To fix the warning, this series of changes sets
-Wno-strict-prototypes on affected third-party dependencies.

The error message is "a function declaration without a prototype is
deprecated in all versions of C". It appears in:
  trees.c
  contrib/minizip/ioapi.c
  contrib/minizip/zip.c
