[PATCH 1/3] gdb/testsuite: fix rust compiler selection in gdb_default_target_compile

[simon.marchi@polymtl.ca]

From: Simon Marchi <simon.marchi@polymtl.ca>

The "set compiler" line looks like a copy-paste error from the if just
above.  If we compare this to the Go handler, then it seems clear that the
intent was to write:

	    if {[board_info $dest exists rustcompiler]} {
		set compiler [target_info rustcompiler]
	    } else {
		set compiler [find_rustc]
	    }

The name rustcompiler follows the convention used by other languages (e.g.
"gocompiler", "dcompiler", etc).

This also matches what was sent upstream to DejaGnu in commit c8beff4a0843
("Add Rust support to default_target_compile").
