[Buildroot] [git commit branch/2025.02.x] support/testing: TestOpenJdk: remove stime() function call

[Thomas Perale]

commit: https://git.buildroot.net/buildroot/commit/?id=c50e95e02688ee4b75585bbecfbd70987fa8c73d
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2025.02.x

stime() has been deprecated in glibc 2.31 [1] and replaced with
clock_settime(). Let's replace the stime() function call used in
BR2_PACKAGE_OPENJDK_JNI_TEST sources with clock_settime().

Apply the same change as busybox [2]. Make sure that timeToSet
has been zeroed.

With that fixed, the test "Call Native Library to Set System Time"
succeed:

  [BRTEST# java -cp /usr/bin JniTest
  Test: Get JNI Version passed
  Test: Read Native String Constant passed
  Test: Write Java String to Native Library passed
  Test: Write Java Char Array to Native Library passed
  Test: Write String Member to Native Library passed
  Test: Set String Member from Native Library passed
  Test: Execeute Java Function from Native Library passed
  Test: Instantiate Java Class passed
  Test: Call Native Library to Set System Time passed
  [BRTEST# echo $?
  0

The last external toolchain using a glibc 2.30 was the Bootlin
aarch64--glibc--bleeding-edge-2020.02-2, so since then TestOpenJdk
is broken.
