SPECS: crun: Align CRIU build condition

[Jingwiw]

Changes

• Make CRIU support follow the existing %bcond criu.

  The spec already has %bcond criu 0 and conditional CRIU BuildRequires. Pass the matching configure option explicitly so the default build disables CRIU instead of relying on configure-time auto probing.

  Source: configure.ac

  AC_ARG_ENABLE([criu], AS_HELP_STRING([--disable-criu], [Disable CRIU based checkpoint/restore support]))
  AS_IF([test "x$enable_criu" != "xno"], [
      PKG_CHECK_MODULES([CRIU], [criu >= 3.15], [have_criu="yes"], [have_criu="no"
          AC_MSG_NOTICE([CRIU headers not found, building without CRIU support])])
      ...
  ], [AC_MSG_NOTICE([CRIU support disabled per user request])])

AIGC Declaration: CodeX with gpt5.5 was used as coding agent.
