getent.1, iconv.1, ldd.1, locale.1, localedef.1, memusage.1, memusagestat.1, pldd.1, sprof.1, time.1: tfix, use a one-font macro for a single argument

1) Use a single capital font macro for a genuine single argument.
  The output is unchanged.

2) Remove quotation marks (") around a single argument.
  The output is unchanged.

3) Change ".IR ab()" to ".IR ab ()"
  A font is changed in the output.

mtk: I verified that the output is unchanged (other than fonts)
by comparing the output of:

    for a in *.1; do man $a >> out.txt; done

before and after the patch.
