file: remove obsolete version check patch

After e8d2a2a3646f964ec61ece62e14788cd7184dd01 [OE-Core], file --version
returns file-5.14 instead of file.real-5.14 so the patch is no longer
necessary and causes the build to fail with the following:
| Cannot use the installed version of file (file-5.14) to
| cross-compile file 5.14
| Please install file 5.14 locally first
