Can you use uintptr_t just to be pedantically correct? It's in linux/types.h so it should be fine.

uintptr_t is not in uapi

Summary: After diving in all the build system I found that the first error mentioned in #219 and #220 ``` 1597 | static_assert(formattable_char, "Mixing character types is disallowed."); ``` Was basically happening while compiling folly, after compiling it by itself I noticed this didn't happened, so I found that there was an issue with the fmt dependencies, removing the one that was downloaded by katran The issue mentioned in: #221 Was because katran was configured to use C++14 by default, and some of the libraries of folly require C++17, updated our requirements.

Tested By:
running katran_tester to make sure that we did not break anything
also this is nop from bpf instructions point of view
