Various installman cleanups.

Eliminate the C<use File::Copy> and various $Is_* vars, unneeded since
commit 9e6fc21fcd859351 moved the code that uses them into install_lib.pl
Move the filename-based skip code into the callback for File::Find::find(),
as this saves ever storing them in %$modpods.
Eliminate @to_process, which has been mostly redundant since commit
a274383458745101, and completely redundant since commits 02bc0c09b2a02ba6^
and 02bc0c09b2a02ba6.
Eliminate the batchlimit command line option, which has been redundant since
commit a274383458745101.
