8377707: [Linux Alpine] Build failure after JDK-8377368

[MBaesken]

On Linux Alpine, we get the following build error:

libproc_impl.h:99:4: error: 'off64_t' does not name a type; did you mean 'off_t'?
   99 | off64_t vdso_offset; // offset of vDSO in core
      | ^~~~~~~
      | off_t

and

jdk/src/jdk.hotspot.agent/linux/native/libsaproc/ps_core.c:639:11: error: implicit declaration of function 'sendfile64'; did you mean 'sendfile'? [-Wimplicit-function-declaration]
  639 | if (sendfile64(lib_fd, ph->core->core_fd, &ofs, ph->core->vdso_size) == -1) {
      | ^~~~~~~~~~
      | sendfile
