lang/nodejs-14.6.0 build failure on NetBSD 8.2

[Frederic Fauberteau <triaxx%NetBSD.org@localhost>]

Dear pkgsrc users,

I created a bug report upstream: https://github.com/nodejs/node/issues/34510

The error is due to a macro from deps/uvwasi/include/wasi_serdes.h that provides declarations of function prototype according to type:
#define BASIC_TYPE_(name, type)                                               \
  void uvwasi_serdes_write_##name(void* ptr, size_t offset, type value);      \
  type uvwasi_serdes_read_##name(const void* ptr, size_t offset);             \

Since (at least) NetBSD 8.2 defines in /usr/include/stdint.h:
#ifndef uint8_t
typedef __uint8_t  uint8_t;
#define uint8_t    __uint8_t
#endif
the resulting declared functions are uvwasi_serdes_{write,read}___uint8_t() instead of uvwasi_serdes_{write,read}_uint8_t() and the compilation errors follow.

I suggest the patch below but I am open to any remark or suggestion that would allow us to provide a solution which respects best practices:
