package/libftdi1: fix static build with libusb and -latomic

Use pkg-config to retrieve libusb dependencies such as -latomic and
avoid the following static build failure raised since bump of libusb to
version 1.0.25 in commit aad609936fc83acfe1eac6ffc86d29ac35dcf54e:

/nvmedata/autobuild/instance-29/output-1/per-package/libftdi1/host/bin/../lib/gcc/sparc-buildroot-linux-uclibc/10.3.0/../../../../sparc-buildroot-linux-uclibc/bin/ld: /nvmedata/autobuild/instance-29/output-1/per-package/libftdi1/host/sparc-buildroot-linux-uclibc/sysroot/lib/libusb-1.0.a(core.o): in function `libusb_unref_device':
/nvmedata/autobuild/instance-29/output-1/build/libusb-1.0.25/libusb/core.c:1186: undefined reference to `__atomic_fetch_add_4'
