nss: Disable Werror across all recipe types

We are seeing warnigs with gcc-10 even on target builds e.g.

| In file included from nsinstall.c:20:
| /usr/include/unistd.h:520:14: note: in a call to function ‘getcwd’ declared with attribute ‘write_only (1, 2)’
|   520 | extern char *getcwd (char *__buf, size_t __size) __THROW __wur
|       |              ^~~~~~
| nsinstall.c:70:16: error: argument 1 is null but the corresponding size argument 2 value is 4096 [-Werror=nonnull]
|    70 | #define GETCWD getcwd
|       |                ^
| nsinstall.c:246:13: note: in expansion of macro ‘GETCWD’

|       |             ^~~~~~
