staging: erofs: complete POSIX ACL support
Let's add .get_acl() to read the file's acl from its xattrs
to make POSIX ACL usable.
Here is the on-disk detail,
fullname: system.posix_acl_access
struct erofs_xattr_entry:
.e_name_len = 0
.e_name_index = EROFS_XATTR_INDEX_POSIX_ACL_ACCESS (2)
fullname: system.posix_acl_default
struct erofs_xattr_entry:
.e_name_len = 0
.e_name_index = EROFS_XATTR_INDEX_POSIX_ACL_DEFAULT (3)
