build: rename --enable-ebpf to --enable-usdt

Browse Source 
eBPF is a Linux kernel technology used to "extend the capabilities
of the kernel without requiring to change kernel source code or
load kernel modules". While Userspace, Statically Defined Tracing
(USDT) uses eBPF under the hood, --enable-usdt better resembles that
support for USDT is enabled, and tracepoints will be included in the
binary.
