GitHub Action failure: undefined reference to `inflate'

[Robert Scheck]

My unrelated documentation-only commit 32b8c63 lead to a GitHub Action failure:

/usr/bin/ld: rpki_client-http.o: in function `http_handle':
http.c:(.text+0x13aa): undefined reference to `inflate'
/usr/bin/ld: http.c:(.text+0x19a6): undefined reference to `inflateReset'
/usr/bin/ld: http.c:(.text+0x19b8): undefined reference to `inflateEnd'

/usr/bin/ld: http.c:(.text+0x4125): undefined reference to `inflateEnd'
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Looks like zlib is a new dependency and should make it into configure etc.?
