[ Upstream commit 61c7aa5020e98ac2fdcf07d07eec1baf2e9f0a08 ]
Ensure libbpf.so is re-built whenever libbpf.map is modified. Without this,
changes to libbpf.map are not detected and versioned symbols mismatch error
will be reported until `make clean && make` is used, which is a suboptimal
developer experience.
Fixes: 306b267cb3 ("libbpf: Verify versioned symbols")
