Nicolas Saenz Julienne b760758c5e rpi-eeprom-update: Use 'tr' instead of 'strings' ...

The 'strings' utility is installed by binutils whereas 'tr' belongs with
coreutils. Minimal systems will only contain the latter, due to binutils'
size (20-50 MB). So, convert all uses of 'strings' to 'tr' so as to
avoid the package dependency.

The second 'tr' usage converts non-ASCII characters into newlines so as
to isolate the "BUILD_TIMESTAMP=1234567890" statement (similar to what
'strings' does). There is no need for this in the first one: non-ASCII
characters are simply discarded as DT aliases have a fixed one line
format.
