Refinements for installing bootstrap / untethered on 64-bit (#797)

* Refinements for installing bootstrap / untethered on 64-bit

* Instead of sending the tar to the RootFS with limited space,
  send it as stdin via SSH.

* Add note for iOS 8 SSH ramdisk

* Add tar with Patcyh removed

This package has a requirement for firmware >= 8.3, which causes
issues for devices running versions older than this.

Fix by removing them from dpkg's available and status lists,
alongside all installed dependencies.

* Allow Cydia to perform stashing on untethered 7.x

"""
 Upon the iOS device, a space doth wane,
 The root partition, small, doth fill apace.
 When tweaks and apps in multitudes we gain,
 The system groans in such a crowded space.

 Then Cydia, wise, a remedy did grace:
 To stash away in user's land more vast,
 The Applications, Themes, and Library's place,
 With symlinks left, so naught is overpassed.

 But LukeZGD, in prudence, held it fast;
 Disabled by default, the stashing art,
 Lest unforeseen mishaps be then amassed,
 And cautious users play the safer part.

 Now, hark! The program grants a choice to start:
 To stash or not, as users may decree.
 Thus freedom rings, a satisfying chart,
 And each may choose as fits their warranty.
 So lift thy voice and let thy choice be free,
 For stashing's power now lies in thine own hand.
"""

This is the original commit message:
Stashing appears to work fine with this set-up, fixing issues with
not enough storage space when installing tweaks.

Users may use Cydia Eraser if they preferred going back to factory
configurations, so this is absolutely fine.
