    New proc supports_get_siginfo_type
    
    Both siginfo-obj.exp and siginfo-thread.exp have the same code
    checking the support of geting a type of siginfo for a given arch.
    This patch is to move these code into a proc supports_get_siginfo_type.
    
    gdb/testsuite:
    
    2015-06-24  Yao Qi  <yao.qi@linaro.org>
    
    	* lib/gdb.exp (supports_get_siginfo_type): New proc.
    	* gdb.base/siginfo-obj.exp: Invoke supports_get_siginfo_type.
    	* gdb.base/siginfo-thread.exp: Likewise.
