cmake lz4: fix wrong CMake target name (groonga#1850)

This patch will fix build error on Arch Linux by adding the fix that was
missing at groonga#1832 .

Arch Linux provides only `LZ4::lz4_shared`. `LZ4::lz4_static` isn't
provided. We always use `LZ4::lz4_static` because of the wrong target
name (`LZ4::liblz4_shared`). But Arch Linux doesn't provide
`LZ4::lz4_static`. So it causes the following build error.
