perf build: Suppress openssl v3 deprecation warnings in libcrypto feature test
With OpenSSL v3 installed, the libcrypto feature check fails as it use the
deprecated MD5_* API (and is compiled with -Werror). The error message is
as follows.
$ make tools/perf
```
Makefile.config:778: No libcrypto.h found, disables jitted code injection,
please install openssl-devel or libssl-dev
Auto-detecting system features:
... dwarf: [ on ]
... dwarf_getlocations: [ on ]
... glibc: [ on ]
... libbfd: [ on ]
... libbfd-buildid: [ on ]
... libcap: [ on ]
... libelf: [ on ]
... libnuma: [ on ]
... numa_num_possible_cpus: [ on ]
... libperl: [ on ]
... libpython: [ on ]
... libcrypto: [ OFF ]
... libunwind: [ on ]
... libdw-dwarf-unwind: [ on ]
... zlib: [ on ]
... lzma: [ on ]
... get_cpuid: [ on ]
... bpf: [ on ]
... libaio: [ on ]
... libzstd: [ on ]
... disassembler-four-args: [ on ]
```
This is very confusing because the suggested library (on my Ubuntu 20.04
it is libssl-dev) is already installed. As the test only checks for the
presence of libcrypto, this commit suppresses the deprecation warning to
allow the test to pass.
