gdb/testsuite: relax filename restriction in some gdb.btrace tests

The test gdb.btrace/tailcall.exp has multiple tests that include the
filename in the output. When testing with gcc, only a relative path is
printed, but when using clang, the full file path is printed instead.
This makes most of those tests fail, with the exception of "record goto
4" which allows for more characters before the file name. The test
gdb.btrace/recod_goto.exp suffers with the same issue

This commit allows for text before the filename. However, instead of how
the aforementioned "record goto 4", it uses a regexp that doesn't allow
for newlines, just in case some off output happens.
