LIST(APPEND ...) treats ( and ) as literal list elements, not grouping
syntax. When libbrotlidec/libbrotlienc are found via pkg-config,
CORE_EXTRA_LIBS_DIRS ends up containing bare "(" and ")" which are then
passed to TARGET_LINK_DIRECTORIES, causing a CMake configure error.
Test plan: reproduced via moxygen's standalone build, which pulls
picoquic (and transitively picotls) via CMake FetchContent. In that
layout picotls source lives inside the build tree, so the relative
path "(" resolves to a build-prefixed path and CMake raises a hard
error. Installing libbrotli-dev/brotli triggers the bug; this fix
resolves it.

I thought about making a CI here for picotls, but it would have been rather involved.
