[SYCL] [xmethods] Allow replacing xmethod script (#1532)

mihails-strasuns-intel · web-flow · commit 042d981eca3c · 2020-04-21T12:54:22.000+03:00
Previous version didn't work when `run` command was issued multiple
times in GDB without terminating the session, as it reloads
libsycl-gdb.py each time shared library is loaded. Explicitly allowing
to replace previous version fixes the problem.
