    [gdb/testsuite] Fix gdb.base/attach-deleted-exec.exp with NFS

    With test-case gdb.base/attach-deleted-exec.exp I ran into:
    ...
    (gdb) attach 121552^M
    Attaching to process 121552^M
    Reading symbols .../attach-deleted-exec/.nfs00000000044ff2ef00000086...^M

    (No debugging symbols found in /lib64/libc.so.6)^M
    Reading symbols from /lib64/ld64.so.2...^M
    (No debugging symbols found in /lib64/ld64.so.2)^M

/lib64/libc.so.6^M
    (gdb) FAIL: $exp: attach to process with deleted executable
    ....

    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)
