fix: give a suffixed release its emulator's tree

_foreign_tree compared owner tokens by equality, so cxbx-reloaded-2023
read bios/Other/cxbx-reloaded/ as another emulator's tree and the
case-folded fallback served xemu's encrypted EEPROM. The leading whole
words of a profile key now name its own tree too. Across every profile
entry this moves cxbx-reloaded-2023's EEPROM.bin to the decrypted dump,
turns eight name matches on the same files into path matches, and gives
solarus-2.0.0 the Solarus tree's gamecontrollerdb.txt.
