sqlite3: remove $(FPIC)

Defaulting to -fPIC is a bad idea, especially for executables (here:
sqlite3-cli). In short, there are certain security implications as well
as overhead/performance penalties. Details see:

https://wiki.gentoo.org/wiki/Project:Hardened/Position_Independent_Code_internals

The configure script is able to detect the need for PIC and adds the
flag when needed anyway (when compiling the library).
