Fix parsing attributes for struct decls

Browse Source 
Given this code:

  struct __attribute__((...)) Name {...};

TCC was eating "Name", hence generating an anonymous struct.
It also didn't apply any packed attributes to the parsed
members.  Both fixed.  The testcase also contains a case
that isn't yet handled by TCC (under a BROKEN #define).
