    alpha: force old OSF1 syscalls for getegid, geteuid and getppid [BZ #24986]
    
    On alpha, Linux kernel 5.1 added the standard getegid, geteuid and
    getppid syscalls (commit ecf7e0a4ad15287). Up to now alpha was using
    the corresponding OSF1 syscalls through:
     - sysdeps/unix/alpha/getegid.S
     - sysdeps/unix/alpha/geteuid.S
     - sysdeps/unix/alpha/getppid.S
    
    When building against kernel headers >= 5.1, the glibc now use the new
    syscalls through sysdeps/unix/sysv/linux/syscalls.list. When it is then
    used with an older kernel, the corresponding 3 functions fail.
    
    A quick fix is to move the OSF1 wrappers under the
    sysdeps/unix/sysv/linux/alpha directory so they override the standard
    linux ones. A better fix would be to try the new syscalls and fallback
    to the old OSF1 in case the new ones fail. This can be implemented in
    a later commit.
