modpost: do not warn about missing MODULE_DESCRIPTION() for vmlinux.o

Browse Source 
[ Upstream commit 9185afeac2 ]

Building with W=1 incorrectly emits the following warning:

  WARNING: modpost: missing MODULE_DESCRIPTION() in vmlinux.o

This check should apply only to modules.

Fixes: 1fffe7a34c ("script: modpost: emit a warning when the description is missing")
