Remove code that would trigger if pcre_config() or pcre2_config() was
so broken that "do we have JIT?" wouldn't return a boolean.
I added this code back in fbaceaac47 ("grep: add support for the PCRE
v1 JIT API", 2017-05-25) and then as noted in f002532784 ("grep: print
the pcre2_jit_on value", 2019-07-22) incorrectly copy/pasted some of
it in 94da9193a6 ("grep: add support for PCRE v2", 2017-06-01).
Let's just remove this code. Being this paranoid about the
pcre2?_config() function itself being broken is crossing the line into
unreasonable paranoia.
