[PATCH iproute2-next 3/7] fix grammar and style issues in man pages for stat related pages

[Stephen Hemminger <stephen@networkplumber.org>]

This patch addresses grammatical errors and style inconsistencies in
the ifstat, lnstat, and rtacct man pages documentation.

lnstat Changes:
  - Capitalize "Linux" as proper noun in NAME and DESCRIPTION sections
  - Add missing period to -j/--json option description
  - Fix passive voice: "is being used" -> "is used"
  - Fix word form: "can not" -> "cannot"

rtacct Changes:
  - Fix date format: remove comma in "27 June, 2007" -> "27 June 2007"
  - Remove period from NAME section per man page convention
  - Capitalize SNMP acronym (2 instances)
  - Add missing periods to -h and -V option descriptions
  - Improve clarity of -s/--noupdate description
  - Add missing article in -d/--scan description

No functional changes. All technical content remains accurate.
