[Patch 1/1 V2] BaseTools: Fix a bug of genffs command generation

["Bob Feng" <bob.c.feng@intel.com>]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2221

The command used by multiple thread genffs feature in makefile
for testing if file exist is generated based on the toolchain family.
It should be based on the make program name.
