FS_METHOD=ssh2 breaks some plugins

[denkoren]

Some plugins expect WS_Filesystem() call to work properly without options.
SSH2 method requires several options to work. When plugin does not call request_filesystem_credentials() it becomes broken by FS_METHOD=ssh2 constant.

WordPress can use FTP_* constants as defaults in WP_Filesystem_SSH2 when none options are provided to constructor.

Thanks for the PR! I think the attachment didn't work because ​https://github.com/WordPress/WordPress is a mirror of the build repo, not the development repo. It should work on ​https://github.com/WordPress/wordpress-develop.

Ticket: https://core.trac.wordpress.org/ticket/50287

Some of plugins expect FS_METHOD to be direct to control their files
They do not ask for credentials and do not expect WP_Filesystem() can
require ones.

This commit makes WP_Filesystem() with FS_METHOD='ssh2' to use FTP_*
constants as default settings when none are provided to constructor.
