    [gdb/testsuite] Fix valgrind tests on debian
    
    On debian 12, I run into:
    ...
    (gdb) target remote | vgdb --wait=2 --max-invoke-ms=2500 --pid=618591^M
    Remote debugging using | vgdb --wait=2 --max-invoke-ms=2500 --pid=618591^M
    relaying data between gdb and process 618591^M
    warning: remote target does not support file transfer, \
      attempting to access files from local filesystem.^M
    Reading symbols from /lib/ld-linux-aarch64.so.1...^M
    (No debugging symbols found in /lib/ld-linux-aarch64.so.1)^M
    0x000000000401a980 in ?? () from /lib/ld-linux-aarch64.so.1^M
    (gdb) FAIL: gdb.base/valgrind-infcall.exp: target remote for vgdb
    ...
    
    The problem is that we're expecting to match either of these regexps:
    ...
            set start_re1 " in \\.?_start "
            set start_re2 "\\.?_start \\(\\) at "
    ...
    but there are no dwarf or elf symbols present.
    
    Fix this by also allowing:
    ...
           set start_re3 "$::hex in \\?\\? \\(\\) from "
    ...
    
    Tested on aarch64-linux.
