libc/inet: Unbreak gethostent()
Although gethostent() is obsoleted, there is no reason to keep it broken. Fix two problems: * commit f65e66078b "resolver: switch to config parser" leave an extra break statement in case of GETHOSTENT in __read_etc_hosts_r. In result, output buffer wasn't initialized at all. * gethostent static buffer has insufficient size to store aliases, so __read_etc_hosts_r always returns ERANGE. Restore ALIAS_DIM define. Add test-case. Signed-off-by: Leonid Lisovskiy <lly.dev@gmail.com>
