GuestAppContent now writes a param.json that declares downloadDataSize 0
and checks that sceAppContentDownloadDataGetAvailableSpaceKb returns OK
with 0 KB for /download0 (it threw before), and PARAMETER for a null
result. TechnicalDebt records that the console's behaviour for such a
title is unverified.

No additional content is installed, so sceAppContentAddcontMount returns
SCE_APP_CONTENT_ERROR_NOT_FOUND with the mount point untouched, and
sceAppContentAddcontUnmount finds no mount to release. A missing label
or mount point is a parameter error. The library gets its own
CMakeLists for the new guest_appcontent test.
