[SRU][G][PATCH 6/8] UBUNTU: SAUCE: Revert "modules: mark each_symbol_section static"

[Ian May]

BugLink: https://bugs.launchpad.net/bugs/1932065

This reverts commit e3636033dba208822b9df6f472b359d6baa34007.

Upstream introduced 'module' patches that removed exported symbols
that might cause potential disruption and breakage for customers.

Reverting as SAUCE patches to prevent regressions.
