[LU-1857] Coverity: Fix 'Unbounded source buffer' errors

• Type: Technical task
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.4.0
• Affects Version/s: Lustre 2.4.0, Lustre 2.1.3
• Labels: build coverity

Description

Thanks to the Coverity tool, we found some memory corruptions in the Lustre code, and more specifically cases of unbounded source buffers.
This is typically where we should use strncpy() instead of strcpy() or snprintf() instead of sprintf() because the size of the source buffer is not known.

I will propose a patch to address the issues.
