riscv: select FTRACE_MCOUNT_USE_PATCHABLE_FUNCTION_ENTRY
In commit afc76b8b8011 ("riscv: Using PATCHABLE_FUNCTION_ENTRY instead
of MCOUNT") RISC-V added support for -fpatchable-function-entry, which
removes the need for recordmcount.
Select FTRACE_MCOUNT_USE_PATCHABLE_FUNCTION_ENTRY to tell the build
system not to run recordmcount.
