bpf: GCC requires function attributes before the declarator

Browse source

GCC insists in placing attributes before the declarators in function
declarations.  Now that GCC supports btf_decl_tag and therefore __tag1
and __tag2 expand to actual attributes, the compiler is complaining
about it for

  static __noinline int foo(int x __tag1 __tag2) __tag1 __tag2

progs/test_btf_decl_tag.c:36:1: error: attributes should be specified \
before the declarator in a function definition

This patch simply places the tags before the declarator.
