[BOLT] Fix unconditional output of boltedcollection in merge-fdata (#78653)

Browse Source 
Fix the bug where merge-fdata unconditionally outputs boltedcollection
line, regardless of whether input files have it set.

Test Plan:
Added bolt/test/X86/merge-fdata-nobat-mode.test which fails without this
fix.
