[PATCH 1/3] grep: make pcre1_tables version agnostic

["Carlo Marcelo Arenas Belón" <carenas@gmail.com>]

6d4b5747f0 ("grep: change internal *pcre* variable & function names
to be *pcre1*", 2017-05-25), renamed most variables to be PCRE1
specific to give space to similarly named variables for PCRE2, but
in this case the change wasn't needed as the types were compatible
enough (const unsigned char* vs const uint8_t*) to be shared.

Revert that change, as 94da9193a6 ("grep: add support for PCRE v2",
2017-06-01) failed to create an equivalent PCRE2 version.
