5225f1b4 - [BOLT][merge-fdata] Fix basic sample profile aggregation without LBR info (#118481)

[BOLT][merge-fdata] Fix basic sample profile aggregation without LBR info (#118481) When a basic sample profile is gathered without LBR info, the generated profile contains a "no-lbr" tag in the first line of the fdata file. This PR fixes merge-fdata to recognize and save this tag to the output file.
