[Buildroot] [PATCH 1/1] package/fakedate: Skip other fakedates in PATH

[Mark Huang]

If multiple buildroot SDKs are in PATH before /usr/bin (usually accidentally,
but there may be some valid use cases for this), the first two copies of
fakedate will go into a loop calling each other without ever finding
/usr/bin/date. Grep for SOURCE_DATE_EPOCH in the candidate date binary, for
additional verification that it's not another copy of fakedate.
