perf genelf: Fix compiling with libelf on rv32
When cross-compiling perf with libelf, the following error occurred:
In file included from tests/genelf.c:14:
tests/../util/genelf.h:50:2: error: #error "unsupported architecture"
50 | #error "unsupported architecture"
| ^~~~~
tests/../util/genelf.h:59:5: warning: "GEN_ELF_CLASS" is not defined, evaluates to 0 [-Wundef]
59 | #if GEN_ELF_CLASS == ELFCLASS64
Fix this by adding GEN-ELF-ARCH and GEN-ELF-CLASS definitions for rv32.
