fix(libScePosixForWebKit): export the host-named functions through a renamed helper

Browse Source 
gethostbyname_r and sysinfo are names of host C library functions. Defining
them in libScePosixForWebKit made the library's own call to
::gethostbyname_r in Resolver.cpp bind to the new declaration, and the
guest_resolver test failed with "gethostbyname_r not implemented". Export
the two NIDs through a helper with the library's own prefix, the way
libSceAmpr re-exports the libc functions.

### Unknown function info
- [gethostbyname](../../../core/libs/prx/libScePosixForWebKit/Resolver.cpp) (libScePosixForWebKit) - numeric IPv4 forms, trailing whitespace and 64-bit accumulation follow FreeBSD 11.4 [inet_aton](https://github.com/freebsd/freebsd-src/blob/releng/11.4/lib/libc/inet/inet_addr.c); clearing the resolver error on numeric success follows [fakeaddr](https://github.com/freebsd/freebsd-src/blob/releng/11.4/lib/libc/net/gethostnamadr.c). Exact PS5 behavior is unverified; hostname lookup still uses the host resolver

These exports use renamed helpers; defining `gethostbyname_r` would interpose on the host function this library calls itself. All are parameterless import stubs, not ABI claims; callers must not use them until signatures are verified.
