Shells based on busybox, such as found in CM 12.1 recovery and TWRP, do not
properly handle pattern based parameter expansion for variables longer than
4kb. This throws our naive little XML parser into an infinite loop. Since
all such lines are associated with external app certs, just skip them.

Rewrite the packages.xml parser to be slightly less brittle. Read
lines from packages.xml and save off the interesting values, then
compare with expected results afterward.
This both avoids using grep's -A option, which is not supported in
toybox, and allows the script to recognize the cert tag regardless
of its position inside the package tag.

If the --wipe_data command is being passed to recovery, skip the
signature check since the data will be wiped after the update is
installed

It appears that some versions of sed do not work with the + symbol.
Instead of checking for one or more digits, check for a digit,
followed by zero or more digits.
