Do not use -Werror during build

There are new warnings when setools are built with gcc 7 therefore we
want to suppress -Werror for now

Fixes:
libqpol/policy_extend.c: In function ‘policy_extend’:
libqpol/policy_extend.c:161:27: error: ‘%04zd’ directive output may be truncated writing between 4 and 10 bytes into a region of size 5 [-Werror=format-truncation=]
