icu: make filtered data generation optional, serial and off by default

Backported from master with two differences:

1. Move exit in do_make_icudata_class-target after big endian patch
application (not required for master since new upstream icu includes
the patch)

2. In do_install_append_class-target test for existence of .dat input
file before calling icupkg

icu data generation was found to be racy, and causig AB failures;
making it serial and leaving it on is not an option as it regresses
to several minutes.

The specific bug is that rules.mk has:

LD_LIBRARY_PATH=../lib:../stubdata:../tools/ctestfw:$LD_LIBRARY_PATH  ../bin/gencnval -s . -d ./out/build/icudt66l mappings/convrtrs.txt

which creates a file and numerous rules like

LD_LIBRARY_PATH=../lib:../stubdata:../tools/ctestfw:$LD_LIBRARY_PATH  ../bin/genrb -s ./misc -d ./out/build/icudt67l -i ./out/build/icudt67l -k -q numberingSystems.txt

which quietly read it. There is no prerequisite for the former to complete first.

The race is extra complicated to fix as rules.mk is itself
generated through a custom in-tree python tool.
