Defining strlcpy here clashes on macOS, which has some compiler magic
around their strlcpy declaration. Fix this by inverting the check
to declare the prototype only if we are on __GLIBC__. As uClibc may
define __GLIBC__ as well, check for absence of its __UCLIBC__.
This is in-line with what Linux has been doing since 0215d59b15
("tools lib: Reinstate strlcpy() header guard with __UCLIBC__").
