convert one more caching proc

Browse Source 
I noticed that skip_btrace_tests is a classic "caching proc" that I
missed when I added gdb_caching_proc.  This patch converts it.

Built and regtested on x86-64 Fedora 18.

	* lib/gdb.exp (skip_btrace_tests): Use gdb_caching_proc and
	standard_temp_file.
