Install: pass the /user/data path Sony allowlists; report per-URI rc

Sony path-allowlists the URI given to sceAppInstUtilInstallByPackage —
/user/data/ and /mnt/usb are accepted, a bare /data/... path is rejected with
0x80B2116F (confirmed by the ps5upload project). PatchDL stored the pkg under
/data/patchdl and passed that /data path, so every install was rejected at the
path stage. Pass the /user/data view of the same file instead (the code already
computed it as sdk_path; it was only used for AppInstallPkg before).

Also report each URI's individual rc instead of only the last attempt's, which
revealed the real wall: via file:// the installer reaches header parsing and
rejects with 0x80B21106 — the assembled file is a valid but DEBUG-magic PKG
(\x7FFIH, not retail \x7FCNT), the format Sony's system updater consumes rather
than the retail-pkg format InstallByPackage expects.
