kbuild: fix ksym_dep_filter when multiple EXPORT_SYMBOL() on the same line
In kernel/cgroup.c there is:
#define SUBSYS(_x) \
DEFINE_STATIC_KEY_TRUE(_x ## _cgrp_subsys_enabled_key); \
DEFINE_STATIC_KEY_TRUE(_x ## _cgrp_subsys_on_dfl_key); \
EXPORT_SYMBOL_GPL(_x ## _cgrp_subsys_enabled_key); \
EXPORT_SYMBOL_GPL(_x ## _cgrp_subsys_on_dfl_key);
The expansion of this macro causes multiple EXPORT_SYMBOL_GPL() instances
to appear on the same preprocessor line output, confusing the sed script
expecting only one of them per line. Unfortunately this can't be fixed
nicely in the sed script as sed's regexp can't do non greedy matching.
Fix this by turning any semicolon into a line break before filtering.
