kbuild: lto: add _mcount to list of used symbols



Some randconfig builds fail with undefined references to _mcount
when CONFIG_TRIM_UNUSED_KSYMS is set:

ERROR: modpost: "_mcount" [drivers/tee/optee/optee.ko] undefined!
ERROR: modpost: "_mcount" [drivers/fsi/fsi-occ.ko] undefined!
ERROR: modpost: "_mcount" [drivers/fpga/dfl-pci.ko] undefined!

Since there is already a list of symbols that get generated at link
time, add this one as well.
