FYI: fix 2 tests when glibc debuginfo is installed

[Tom Tromey <tromey@redhat.com>]

I'm checking this in.

I found a couple of tests that work by accident when glibc debuginfo is
installed.

First, when running attach-stopped.exp:

    break 30
    Breakpoint 1 at 0x3a160d2d30: file ../sysdeps/unix/syscall-template.S, line 63. (7 locations)

This is not what is intended:

    # This breakpoint is there for old/non-x86 kernels not restarting syscalls.
    gdb_breakpoint [gdb_get_line_number "Second sleep"]

Second, attachstop-mt.exp:

    break 30
    Breakpoint 1 at 0x3a160d2d30: file ../sysdeps/unix/syscall-template.S, line 63. (7 locations)

Again:

    gdb_breakpoint [gdb_get_line_number "cut the sleep time"]

The fix is to add $srcfile to the linespec.

	* gdb.threads/attachstop-mt.exp: Add $srcfile to the linespecs.
	* gdb.threads/attach-stopped.exp (corefunc): Add $srcfile to the
	linespec.
