build script --group/owner param of tar not support on Mac

[joaner]

When I run ./build-php7.sh on Mac OS, the last step tar was failed.

what happend:

+ tar --numeric-owner --group=0 --owner=0 -cjvf /Users/mac/openrasp/rasp-php.tar.bz2 rasp-php-2019-09-23
tar: Option --group=0 is not supported

Mac's built-in tar is bsdtar, which is different from the gnutar(linux's built-in) support parameters of the Linux system.

expected:

+ tar -cjvf /Users/mac/openrasp/rasp-php.tar.bz2 rasp-php-2019-09-23
success on linux(gnutar) and mac(bsdtar)

I suggest remove the last step tar, or removing incompatible parameters --group --owner of tar

Use gnu-tar instead, e.g brew install gnu-tar
