cppc_show_perf_and_freq() uses int64_t without including the header that
defines it. Building cpupower against musl fails with "unknown type name
'int64_t'" because the other included headers do not provide the type.
Include stdint.h directly instead of relying on transitive declarations
from other C library headers.
Fixes: 68f34fad760b ("cpupower: Add generic CPPC performance display")
