modpost: Include '.text.*' in TEXT_SECTIONS
Commit 6c730bfc894f ("modpost: handle -ffunction-sections") added ".text.*" to the OTHER_TEXT_SECTIONS macro to fix certain section mismatch warnings. Unfortunately, this makes it impossible for modpost to warn about section mismatches with LTO, which implies '-ffunction-sections', as all functions are put in their own '.text.<func_name>' sections, which may still reference functions in sections they are not supposed to, such as __init. Fix this by moving ".text.*" into TEXT_SECTIONS, so that configurations with '-ffunction-sections' will see warnings about mismatched sections.
