fsstress: fix attr_set naming

Back in 2020 I converted attr_set to lsetxattr, but neglected to notice
that the attr name now has to have the prefix "user." which attr_set
used to append for us.  Unfortunately nobody runs fsstress in verbose
mode so I didn't notice until now, and even then only because fuse2fs
stupidly accepts any name, even if that corrupts the filesystem.

Found by running generic/642 on fuse2fs.
