[bug-libunistring] Fix quoting in exported.sh.in, allow multiple arguments.

[Ralf Wildenhues]

Hi Bruno,

the global symbol pipe text may contain TABs that should not be
flattened; I *think* they were added as a safety measure only, but am
not sure, there are a few oddball nm implementations out there.

The multi-file change allows for further improvements to the build
system.

A similar patch applies to gettext/gettext-tools/libgettextpo.

Cheers,
Ralf
