The filter has a regex looking for a literal '{' in the beginning of a
line. Some awk implementations interpret this as a meta character, so
the regex is deemed broken. Example with busybox awk (POSIX):
`root@hank2:~# kamctl ps`
`awk: bad regex '^{.+"id"[ ]*:[ ]*[0-9]+[ ]*}$': Invalid contents
of {}`
`root@hank2:~#`
To fix this enclose the character in square brackets. This always
matches for a literal '{' and is portable.

#### Description
Hi all,
I was trying to run kamctl on OpenWrt and the regex failed. I found a (closed)
issue and the remedy was to use gawk. But it's actually easy to fix in the
regex and when I can run busybox awk I can't save the space which would be
needed for gawk. OpenWrt is usually run on embedded so space is often an issue
:)
Thanks for looking at this!
Kind regards,
Seb
