Address security concerns reported by 'gosec'

gosec reports several issues, none of them looks very critical. With
this change the following concerns have been addressed:

[pkg/cephfs/nodeserver.go:229] - G302: Expect file permissions to be 0600 or less (Confidence: HIGH, Severity: MEDIUM)
  > os.Chmod(targetPath, 0777)

[pkg/cephfs/util.go:39] - G204: Subprocess launched with variable (Confidence: HIGH, Severity: MEDIUM)
  > exec.Command(program, args...)

[pkg/rbd/nodeserver.go:156] - G302: Expect file permissions to be 0600 or less (Confidence: HIGH, Severity: MEDIUM)
  > os.Chmod(stagingTargetPath, 0777)

[pkg/rbd/nodeserver.go:205] - G302: Expect file permissions to be 0600 or less (Confidence: HIGH, Severity: MEDIUM)
  > os.OpenFile(mountPath, os.O_CREATE|os.O_RDWR, 0750)

[pkg/rbd/rbd_util.go:797] - G304: Potential file inclusion via variable (Confidence: HIGH, Severity: MEDIUM)
  > ioutil.ReadFile(fPath)

[pkg/util/cephcmds.go:35] - G204: Subprocess launched with variable (Confidence: HIGH, Severity: MEDIUM)
  > exec.Command(program, args...)

[pkg/util/credentials.go:47] - G104: Errors unhandled. (Confidence: HIGH, Severity: LOW)
  > os.Remove(tmpfile.Name())

[pkg/util/credentials.go:92] - G104: Errors unhandled. (Confidence: HIGH, Severity: LOW)
  > os.Remove(cr.KeyFile)

[pkg/util/pidlimit.go:74] - G304: Potential file inclusion via variable (Confidence: HIGH, Severity: MEDIUM)
  > os.Open(pidsMax)
