[fix] Deploy scp-hosts use fullpath avoid dangling (#10249)

This path fix error modify worker application.yaml when
running `scp-hosts.sh` script in different directory. Currently
setting only work when running `scp-hosts.sh` in path
`<DOLPHINSCHEDULER_HOME>/bin` using command `./scp-hosts.sh`.
And will fail when we run script in directory
`<DOLPHINSCHEDULER_HOME>` using command `./bin/scp-hosts.sh`

ref: #10209 and #10208
