selftests/bpf: Use common CFLAGS for urandom_read

The urandom_read helper and its shared library are built with $(CLANG)
directly rather than through the normal selftest $(CC) rules.

The CFLAGS variable can contain specific flags only for $(CC) but might
be imcompatible for $(CLANG) and those flags are not necessarily valid
for the clang-only urandom_read build.

Split the BPF selftest local flags into COMMON_CFLAGS and append them to
CFLAGS for the normal build path. Use COMMON_CFLAGS directly for
urandom_read and liburandom_read.so, while still filtering out -static as
before.
