build.yml for Android xmake build

[guri87-byte]

Covering Android builds for armv7a and x86_64.

Currently failing with errors mentioned by several users (libbpf/bpftool#120)

Getting the error at compile stage:

[ 12%]: compiling.bpf uprobe.bpf.c
[ 12%]: compiling.bpf bootstrap.bpf.c
[ 12%]: compiling.bpf minimal_legacy.bpf.c
libbpf: map 'my_pid_map': unsupported map linkage static.
Error: failed to open BPF object file: Operation not supported
error: execv(bpftool gen skeleton build/.gens/minimal_legacy/android/x86_64/release/rules/bpf/minimal_legacy.bpf.o) failed(161)
Error: Process completed with exit code 255

@waruqi, can you please help users with xmake-related setup and problems? Thanks!

#130
