toi-fixes-3.16: fix resume_file undefined error

If TOI parts are compiled as modules:

===
CONFIG_TOI_CORE=y
CONFIG_TOI_FILE=m
CONFIG_TOI_SWAP=m
CONFIG_TOI_CRYPTO=m
CONFIG_TOI_USERUI=m
===

we get the following error:

===
ERROR: "resume_file" [kernel/power/tuxonice_file.ko] undefined!
ERROR: "resume_file" [kernel/power/tuxonice_bio.ko] undefined!
scripts/Makefile.modpost:90: recipe for target '__modpost' failed
make[1]: *** [__modpost] Error 1
===

So just export resume_file variable from hibernate.c to fix the issue.
