Just add an exit at the end, so it will exit after the first match
Code:
awk -v LogText="$Log_Text" '{  
MSG_VALUE=gensub(/^.*message=([A-Za-z0-9]+).*$/,"\\1", 1,LogText)  
print MSG_VALUE
exit
  }'

setcap

SETCAP(8)						      System Manager's Manual							 SETCAP(8)

NAME

       setcap - set file capabilities

SYNOPSIS

       setcap [-q] [-v] (capabilities|-|-r) filename [ ... capabilitiesN fileN ]

DESCRIPTION

       In  the	absence  of  the -v (verify) option setcap sets the capabilities of each specified filename to the capabilities specified.  The -v
       option is used to verify that the specified capabilities are currently associated with the file.

       The capabilities are specified in the form described in cap_from_text(3).

       The special capability string, '-', can be used to indicate that capabilities are read from the standard input. In such cases, the capabil-
       ity set is terminated with a blank line.

       The special capability string, '-r', is used to remove a capability set from a file.

       The -q flag is used to make the program less verbose in its output.

EXIT CODE

       The setcap program will exit with a 0 exit code if successful. On failure, the exit code is 1.

       cap_from_text(3), cap_set_file(3), getcap(8)
