[PATCH 1/3] qemu/compiler: Simplify as all compilers support attribute 'gnu_printf'

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

Since commit efc6c070aca ("configure: Add a test for the minimum
compiler version") the minimum compiler version required for GCC
is 4.8, which supports the gnu_printf attribute.

We can safely remove the code introduced in commit 9c9e7d51bf0
("Move macros GCC_ATTR and GCC_FMT_ATTR to common header file").
