Subject: [PATCH] build: ICU must appear as Requires in pkgconfig
References: https://github.com/libical/libical/pull/244

libical.pc specifies -licu-i18n in its Libs: field,
but no Requires: icu-i18n. As a result, the automatic dependency
generator in Linux distributions won't see the ICU requirement,
won't install it, and builds of secondary software fails.

$ gcc icalthing.c `pkg-config libical --cflags --libs`
[...]
gcc: error: /usr/lib64/libicuuc.so: No such file or directory

Move ICU from Libs to Requires, so the dependency scanner can do its
job. Specifically move it to Requires.private, since specifying -licu*
is not normally needed when libical is a shared library since it
already has it recorded in the ELF.
