busybox: add glibc dependency for vi regex option

Build with musl libc fails with BUSYBOX_DEFAULT_FEATURE_VI_REGEX_SEARCH
enabled. Enabling BusyBox's vi regex search option depends upon GNU
regex.  Musl libc does not support GNU regex[1].

So this patch adds explicit dependency on GNU libc and while at it
remove the FIXME comment.
