riscv: Select HAVE_DYNAMIC_FTRACE when -fpatchable-function-entry is available
clang prior to 13.0.0 does not support -fpatchable-function-entry for
RISC-V.
clang: error: unsupported option '-fpatchable-function-entry=8' for target 'riscv64-unknown-linux-gnu'
To avoid this error, only select HAVE_DYNAMIC_FTRACE when this option is
not available.
Fixes: afc76b8b8011 ("riscv: Using PATCHABLE_FUNCTION_ENTRY instead of MCOUNT")
