[GLIB] Do not resolve '-apple-system' font to default system font
https://bugs.webkit.org/show_bug.cgi?id=209727

Reviewed by Carlos Garcia Campos.

Follow-up to 312073@main.

After 312073@main, Apple system fonts such as '-apple-system' or
'-apple-system-font' are resolved to the default system's font in GLIB ports.

That change produced a regression in how pages using '-apple-system'
fonts are rendered in GLIB ports since, in case the font could not be
resolved, any potential fallback font stated in a page's stylesheet wouldn't
get applied.

Thus, this new patch restores the previous behaviour in which
'-apple-system' fonts do not map to the default system's font in GLIB
ports. In fact, now '-apple-system' fonts exit early to save time trying
to resolve that font.
