[ANNOUNCE] erofs-utils: release 1.2.1

[Gao Xiang]

Hi folks,

A new version erofs-utils 1.2.1 is available at:
git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs-utils.git tags/v1.2.1

This is a quick release addressing recent reported issues since v1.2:
 - fix reported build issues due to different corner configurations;
 - (mkfs.erofs, AOSP) fix sub-directory prefix for canned fs_config.

Thanks,
Gao Xiang
