Build: Support make test when PROG_SUFFIX is used

[zhijun42]

Closes #2883

Support a new environment variable VALKEY_PROG_SUFFIX in the test framework, which can be used for running tests if the binaries are compiled with a program suffix. For example, if the binaries are compiled using make PROG_SUFFIX=-alt to produce binaries named valkey-server-alt, valkey-cli-alt, etc., run the tests against these binaries using VALKEY_PROG_SUFFIX=-alt ./runtest or simply using make test.

Now the test with the make variable PROG_SUFFIX works well.

% make PROG_SUFFIX="-alt"
		...
		...
		CC trace/trace_aof.o
    LINK valkey-server-alt
    INSTALL valkey-sentinel-alt
    CC valkey-cli.o
    CC serverassert.o
    CC cli_common.o
    CC cli_commands.o
    LINK valkey-cli-alt
    CC valkey-benchmark.o
    LINK valkey-benchmark-alt
    INSTALL valkey-check-rdb-alt
    INSTALL valkey-check-aof-alt

Hint: It's a good idea to run 'make test' ;)
% 
% make test                                                                
cd src && /Library/Developer/CommandLineTools/usr/bin/make test
    CC Makefile.dep
    CC release.o
    LINK valkey-server-alt
    INSTALL valkey-check-aof-alt
    INSTALL valkey-check-rdb-alt
    LINK valkey-cli-alt
    LINK valkey-benchmark-alt
Cleanup: may take some time... OK

The failed module test tests/unit/moduleapi/rdbloadsave.tcl seems irrelevant to my PR.
