perf genelf: Fix compiling with libelf on rv32

Browse Source 
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.
