Greptile Summary

This PR disables XPMEM in SLES driver builds by adding --without-xpmem and --without-xpmem-modules to the install.pl invocation.

Changes are applied consistently across:

• the SLES Dockerfile precompiled build step,
• the bash entrypoint SLES source-build flags, and
• the Go-based entrypoint SLES build flags and its unit test expectation.

Net effect: SLES builds should no longer attempt to build/package xpmem components, aligning SLES behavior with the existing approach of excluding optional modules during driver build.

Confidence Score: 5/5

• This PR is safe to merge with minimal risk.
• The change is a narrow, consistent flag addition across Dockerfile, bash entrypoint, Go entrypoint, and tests; no interface changes or control-flow changes were introduced.
• No files require special attention
