TUI: avoid calling strcpy() on identical string objects

In tui_set_source_content(), when offset == 0 the source and destination
pointers of the call to strcpy() are actually the same.  In this case
not only is strcpy() unnecessary but it is also UB when the two strings
overlap.

gdb/ChangeLog:

* tui/tui-source.c (tui_set_source_content): Avoid calling
strcpy() when offset is 0.
