gmacros.h: raise minimum GCC version for attribute __noreturn__

Browse Source 
`#define G_GNUC_NORETURN __attribute__((__noreturn__))` was previously under
`#if G_GNUC_CHECK_VERSION(2, 4)`.

But `# define G_NORETURN __attribute__ ((__noreturn__))` was under
`#if G_GNUC_CHECK_VERSION(2, 8) || (0x5110 <= __SUNPRO_C)`.

Take the latter for `g_macro__has_attribute(__noreturn__)` fallback. This will
disable `G_GNUC_NORETURN` for GCC 2.4-2.7 though.
