Move 'is_regular_file' from common-utils.c to filestuff.c
There is no reason for 'is_regular_file' to be in common-utils.c; it
belongs to 'filestuff.c'. This commit moves the function definition
and its prototype to the appropriate files.
The motivation behind this move is a failure that happens on certain
cross-compilation environments when compiling the IPA library, due to
the way gnulib probes the need for a 'stat' call replacement. Because
configure checks when cross-compiling are more limited, gnulib decides
that it needs to substitute the 'stat' calls its own 'rpl_stat';
however, the IPA library doesn't link with gnulib, which leads to an
error when compiling 'common-utils.c':

The most simple fix for this problem is to move 'is_regular_file' to
'filestuff.c', which is not used by IPA. This ends up making the
files more logically organized as well, since 'is_regular_file' is a
file operation.
No regressions found.
