package/libvirt: disable stack-protector

Browse Source 
Set warning_level to 1 instead of the default value of 2 to disable
stack-protector and avoid the following build failure since the addition
of the package in commit ccfc90e101:

/tmp/instance-5/output-1/host/opt/ext-toolchain/bin/../lib/gcc/i686-buildroot-linux-uclibc/9.3.0/../../../../i686-buildroot-linux-uclibc/bin/ld: tests/commandhelper.p/commandhelper.c.o: in function `printInput':
commandhelper.c:(.text+0xad): undefined reference to `__stack_chk_guard'
