    [gdb/testsuite] Fix gdb.threads/threadcrash.exp with glibc debuginfo
    
    After installing glibc debuginfo, I ran into:
    ...
    FAIL: gdb.threads/threadcrash.exp: test_live_inferior: \
      $thread_count == [llength $test_list]
    ...
    
    This happens because the clause:
    ...
            -re "^\r\n${hs}main$hs$eol" {
    ...
    which is intended to match only:
    ...
     #1  <hex> in main () at threadcrash.c:423^M
    ...
    also matches "remaining" in:
    ...
     #1  <hex> in __GI___nanosleep (requested_time=<hex>, remaining=<hex>) at \
       nanosleep.c:27^M
    ...
    
    Fix this by checking for "in main" instead.
    
    Tested on x86_64-linux.
