Docs/admin-guide/mm/damon/start: mention the dependency as sysfs instead of debugfs
'Getting Started' document of DAMON says DAMON user-space tool, damo[1],
is using DAMON debugfs interface, and therefore it needs to ensure debugfs
is mounted. However, the latest version of the tool is using DAMON sysfs
interface. Moreover, DAMON debugfs interface is going to be deprecated as
announced by commit b18402726bd1 ("Docs/admin-guide/mm/damon/usage:
document DAMON sysfs interface").
This commit therefore update the document to tell readers about DAMON
sysfs interface dependency instead and never mention about debugfs
interface, which will be deprecated.
