From: Sam James <sam@xxxxxxxxxx>
On musl, _PATH_NSSWITCH_CONF won't be defined (it doesn't support NSS),
so let's give it a dummy path when it's not defined by glibc.
Fixes build failures like:
```
../include/nsswitch.h:27:23: error: '_PATH_NSSWITCH_CONF' undeclared (first use in this function)
27 | #define NSSWITCH_FILE _PATH_NSSWITCH_CONF
| ^~~~~~~~~~~~~~~~~~~
```
