base-files: remove ending colon from default $PATH for root user
now the PATH for root user defined in a problematic way PATH=$PATH:/usr/local/sbin:/usr/sbin:/sbin: from eglibc: /* Two adjacent colons, or a colon at the beginning or the end of `PATH' means to search the current directory. */ that means current directory is always searched as the last path, which could generate undesired behavior. One example is found in LTP cron_deny01 test, which always complains "sh: cron_deny01 not found" cron_deny01 is a shell script which setups the initial test preparation and then invokes itself for real test under a different user: su $TEST_USER1 -c "$0" 'su' doesn't inherit PATH into the sub-shell, and thus $0 has to be an absolute path to have right script found. ltp appends the path of cron_deny01 to $PATH before running the test: export PATH="${PATH}:${LTPROOT}/testcases/bin" In ideal way "${LTPROOT}/testcases/bin/cron_deny01" is found and becomes $0, which works well. However due to the ending colon in original PATH: PATH=/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin::${LTPROOT}/testcases/bin $0 becomes 'cron_deny01' w/o leading path which makes sub-shell under 'su' failed to locate cron_deny01. remove ending colon then fixes this problem.
