Fix CONFIG_MODULES=no Linux kernel config
When configuring as builtin (--enable-linux-builtin) for kernels without loadable module support (CONFIG_MODULES=n) only the object file is created. Never a loadable kmod. Update ZFS_LINUX_TRY_COMPILE to handle this in a manor similar to the ZFS_LINUX_TEST_COMPILE_ALL macro.
