vmlinux.lds.h: Fix incomplete .text.exit discards
Enabling CONFIG_GCOV_PROFILE_ALL=y causes linker errors on ARM:
`.text.exit' referenced in section `.ARM.exidx.text.exit':
defined in discarded section `.text.exit'
`.text.exit' referenced in section `.fini_array.00100':
defined in discarded section `.text.exit'
And related errors on NDS32:
`.text.exit' referenced in section `.dtors.65435':
defined in discarded section `.text.exit'
The gcov compiler flags cause certain compiler versions to generate
additional destructor-related sections that are not yet handled by the
linker script, resulting in references between discarded and
non-discarded sections.
Since destructors are not used in the Linux kernel, fix this by
discarding these additional sections.
