Stanislav Fomichev 946152b3c5 selftests/bpf: test_progs: switch to open_memstream
Use open_memstream to override stdout during test execution.
The copy of the original stdout is held in env.stdout and used
to print subtest info and dump failed log.

test_{v,}printf are now simple wrappers around stdout and will be
removed in the next patch.

v5:
* fix -v crash by always setting env.std{in,err} (Alexei Starovoitov)
* drop force_log check from stdio_hijack (Andrii Nakryiko)

v4:
* one field per line for stdout/stderr (Andrii Nakryiko)

v3:
* don't do strlen over log_buf, log_cnt has it already (Andrii Nakryiko)

v2:
* add ifdef __GLIBC__ around open_memstream (maybe pointless since
  we already depend on glibc for argp_parse)
* hijack stderr as well (Andrii Nakryiko)
* don't hijack for every test, do it once (Andrii Nakryiko)
* log_cap -> log_size (Andrii Nakryiko)
* do fseeko in a proper place (Andrii Nakryiko)
* check open_memstream returned value (Andrii Nakryiko)
