[GN] Add -Wno-unused-result on Linux
fread is used in putil.cpp without examining the return value. Suppress
this warning for ICU code only.
This is done for chromium/m49 branch (that can be used for head, too)
because origin/master is already ICU 56.1 that does not need this
warning to be suppressed.
