commit 63a0c13c46476380549bf2c9e22aa4f8f1d667f9

Add liburing dependency check for PAX storage
Add AC_CHECK_LIB check for liburing in the PAX dependency block
to detect missing liburing-devel early during configure phase.
PAX storage requires liburing for io_uring-based fast I/O. This
check prevents unclear linker errors during compilation.
