[gdb/testsuite] Fix gdb.base/attach-deleted-exec.exp with NFS
With test-case gdb.base/attach-deleted-exec.exp I ran into:
...

....
The .nfs file indicates:
- that the file has been removed on the NFS server, and
- that the file is still open on the NFS client.
Fix this by detecting this situation, and declaring the test for filename
/proc/PID/exe unsupported.
Tested on:
- x86_64-linux (setup without NFS)
- ppc64le-linux (setup with NFS)
