Use released tarball rather than github helper.  The tarball does not
contain the open-vm-tools sub directory, so adjust the paths in the patches
to match and drop OPENVMTOOLS_SUBDIR.

Drop 0001-has_bsd_printf.patch: msgList.c has been removed upstream since:
https://github.com/vmware/open-vm-tools/commit/dc81979e78e1b8f42639aeb7aaec69f7ea49eb79

Drop 0004-uclibc_secure_getenv.sh: uClibc-ng provides secure_getenv() since
1.0.22.

Renumber remaining patches.

Add hash for license file.
