criu/config.c: added cli option for build-id
file_validation_method field added to cr_options structure in
"criu/include/cr_options.h" along with the constants:
FILE_VALIDATION_FILE_SIZE
FILE_VALIDATION_BUILD_ID
FILE_VALIDATION_DEFAULT (Equal to FILE_VALIDATION_BUILD_ID)
Usage and description information is yet to be added
Usage:
--file-validation="filesize" (To use only the file size check)
--file-validation="buildid" (To try and use only the build-id check)
