fix: copy mysqlsh lib/mysqlsh/ directory (not just .so files)

mysqlsh expects lib/mysqlsh/ to exist as a subdirectory — it checks
for this at startup and aborts with "lib folder not found, shell
installation likely invalid" if missing.

Previously we copied individual .so files flat into lib/ which
didn't create the required lib/mysqlsh/ structure.
