Fix projectile-replace on Emacs 27+ (#1748, #1741)

Two bugs in projectile-replace:

1. fileloop is autoloaded but never required, so (fboundp
   #'fileloop-continue) returns nil and the function falls back to the
   legacy Emacs 25/26 code path even on Emacs 27+.  Fix by requiring
   fileloop before the check.

2. fileloop-initialize-replace expects a regexp, but projectile-replace
   is documented to do literal replacement.  Fix by wrapping the search
   term with regexp-quote.
