fix: explicitly disable '-Wsuggest-attribute=format'

Some older GCC version seems to enable '-Wsuggest-attribute=format' with
'-Wall' which results in unwanted warnings. Fixing this would require
modifications to the public headers which were done in the master
branch. As a fix for this stable branch, explicitly disable this warning
if the compiler supports it.
