[gdb/testsuite] Drop src arg of MACRO_AT_{func,range}

The dwarf assembly procs MACRO_AT_func and MACRO_AT_range have a src
parameter, which is set to $srcdir/$subdir/$srcfile in every single call.

Drop the src parameter and hardcode usage of $srcdir/$subdir/$srcfile in the
procs.

Build and reg-tested on x86_64-linux.
