[OE-Core][RFC][PATCH 1/3] oeqa/target/ssh: update options for SCP

["Alexis Lothoré" <alexis.lothore@bootlin.com>]

Add two options for SCP:
- by default scp expects sftp server to be available on target, which is
  not always true (e.g: core-image-minimal image). Pass -O to force SCP to
  fallback to legacy SCP protocol
- by default scp expects files. Passing -r option allows to copy
  directories too
