mongodb: Keep build paths out of buildInfo

By default buildInfo embeds the compiler version string and CCFLAGS,
CXXFLAGS and LINKFLAGS, which carry --sysroot and -ffile-prefix-map
paths into mongod and mongos and trigger buildpaths QA warnings. Pass
a variables file that drops those entries from
MONGO_BUILDINFO_ENVIRONMENT_DATA.
