[PATCH] perf build: Fix a compiler error in util/libbfd.c

[Namhyung Kim <namhyung@kernel.org>]

The bfd_boolean type was gone and converted to the standard bool type
but we have some old code that uses the type.  It caused a failure in
the build test.

  util/libbfd.c: In function 'slurp_symtab':
  util/libbfd.c:94:9: error: unknown type name 'bfd_boolean'
     94 |         bfd_boolean dynamic = FALSE;
        |         ^~~~~~~~~~~
  util/libbfd.c:94:31: error: 'FALSE' undeclared (first use in this function)
     94 |         bfd_boolean dynamic = FALSE;
        |                               ^~~~~
  util/libbfd.c:94:31: note: each undeclared identifier is reported only once for each function it appears in
  util/libbfd.c:102:27: error: 'TRUE' undeclared (first use in this function)
    102 |                 dynamic = TRUE;
        |                           ^~~~

Fix it with standard bool type and constants.
