memory-monitor: Add error tolerance to memory allocation logging in h…

…andler script.

Allow the memory-monitor-handler script to proceed even if no memory
allocation sites are found in `logread` output. Previously, if `logread`
returned no matches for "logMemAllocationSites," the script would
terminate due to `set -e`. This change adds `|| :` to handle the
potential absence of matches, enabling the script to continue executing
subsequent commands.
