[Buildroot] [PATCH 02/11] support/download: fix scp download with scheme prefix 'scp://'

[Thomas De Schampheleire <patrickdepinguin@gmail.com>]

From: Thomas De Schampheleire <thomas.de_schampheleire@nokia.com>

The scp download helper is broken when the server URL starts with 'scp://'.
Such prefix is used in two situations:
1. to let FOO_SITE point to an scp location without explicitly having to set
   'FOO_SITE_METHOD = scp'

2. when BR2_PRIMARY_SITE or BR2_BACKUP_SITE points to an scp location. In
   this case, there is no equivalent of 'SITE_METHOD'.

Strip out the scheme prefix, similarly to how the 'file' download helper
does it. That helper has the same cases as above.
