imx: hab: fix srktool -c usage by removing spaces

The srktool option -c does not allow spaces between certificate
filenames. Only commas (',') should separate the filenames. If spaces
are incorrectly included, srktool will not display an error or warning
message but will only process the first certificate in the list.

So adapt documentation accordingly.

The srktool can be used for generating the SRK Table and its respective SRK
Table Hash.
Table Hash (certificate filenames must be separated by ',' without spaces).
- Generating SRK Table and SRK Hash in Linux 64-bit machines:
$ CA_CRT="sha256_2048_65537_v3_ca_crt.pem"
$ ../linux64/bin/srktool -h 4 -t SRK_1_2_3_4_table.bin -e \

The SRK_1_2_3_4_table.bin and SRK_1_2_3_4_fuse.bin files can be used in further
