run-uninstalled: Exit if run from outside the global build root
If uninstalled then Tracker SPARQL must be run from the build directory, otherwise loading the internal parser module might fail, for example:
Tracker:ERROR:../subprojects/tracker/src/libtracker-common/tracker-parser.c:109:ensure_init_parser: assertion failed: (module != NULL)
Bail out! Tracker:ERROR:../subprojects/tracker/src/libtracker-common/tracker-parser.c:109:ensure_init_parser: assertion failed: (module != NULL)
