Feature/add libcurl dependency (#175)

* build: add libcurl-dev to Dockerfiles

OpenMS core library now uses libcurl instead of Qt Network for HTTP
operations. Add the development packages so the build can find
curl headers and libraries.

* build: add -fPIC to static libcurl build

Add CMAKE_POSITION_INDEPENDENT_CODE=ON to the curl cmake configuration.
Without this, the static libcurl.a contains position-dependent relocations
(R_X86_64_32S) that cannot be linked into libOpenMS.so, causing linker
failures on Linux wheel builds.
